The ... Dimorphism Spectrum Tapestry Multiple Filters In Play
The manifestation of the Sexual Dimorphism Personality Spectrum Tapestry is a result of the influence of ALL of the Filters, Ensembles, and Tapestries related to human perception, response, and behavior.

Sexual Dimorphism is instinctive within the Cognitive Me. "It is not taught. It is there."

Therefore a listing of the various other filters that impact the manifestation of the Resilience Personality Spectrum Tapestry would in fact list ALL OF THEM.

We will list a few.

All of the Personality Filters are in play when it comes to wanting to fully understand Sexual Dimorphism, because they are all in play when wanting to fully understand The Me.



The Sexual Personality Dimorphism Spectrum Tapestry
Let's look at some of the various (normal and alternate) mammalian sexual chromosome environments that impact other traits that arise from the non-sexual autosomal chromosome domain. The XY sex-determination system.

Recall that as eukaryotes, our somatic cells are diploid. One haploid copy is contributed by the mother, and the other haploid copy is contributed by the father. The chromosomes are all packaged together in the cellular nucleus. Each of the autosomes is paired with its corresponding autosomal partner ... chromosome 1 with 1, 2 with 2, etc.

The allosomes (the X and Y chromosomes in mammals) are an exception to the rule of 1 with 1, 2 with 2, etc. The X and the Y chromosomes (allosomes) differ from each other and yet may be paired with each other (normally as either XX or XY). When two X's pair with each other (one from the father, the other from the mother) the result is a female. When an X and a Y pair with each other the result is a male.

It turns out that the X:Y ratio is a significant determinant with regard to how eukaryotes develop physically. The genes present on these allosomes are different. Thus, an XX (a genetic female) has twice the X gene dosage of an XY (a genetic male), and it has none of the Y genes. The XY has only half the X gene dosage that an XX has, and it has the Y genes that an XX does not have. Ultimately, all hereditary physical and behavioral traits are gene based. Thus, XX and XY individuals of the same species will manifest differing physical and behavioral attributes.

The Dimorphism Spectrum Tapestry, which we all have manifested with one another. From this, The Sexual Dimorphism Spectrum Tapestry, which describes the various differences between the male and female demographics that comprise our species. A subset of this is The Sexual Personality Dimorphism Spectrum Tapestry.

An understanding of the Asymmetry of the Filters suggests that to even get close to being able to understand another empathetically ("Do I know what it may be like to be You in Your shoes?") one needs to be expressing the same filters and most of them at very similar dial settings. Perfect matches are impossible (a Fundamental Prerequisite) but we often get close enough. However, achieving "close enough" filter matches between XX and XY individuals is completely impossible due to the gene dosage issues and the way that differing X:Y ratios impact physical, cognitive, and experiencial filter development.

We may be able to get along. But we will not truly "get" each other. Close enough is not "getting each other." How close is "close enough" anyway?

Stereotypical asymmetric "getting it" is often observed. Most guys "get" most guys and most "gals" get most "gals". Yet the males often think they get the females ... but generally don't. And the females often think they get the males ... but generally don't. This leads to communication differences depending on the gender one is communicating with, giving rise to the notion of quad-dimensional (i.e. XX to XX, XY to XY, XX to XY, and XY to XX) entendres!

While rare, various divergences from genetic "normalcy" occur throughout all species. Let's examine the more commonly seen X:Y ratio types.
  • XX
    • condition 1 - results in normal female

    • condition 2 (intersex) - XX male syndrome - a rare syndrome diagnosed in 1:20,000 males, 90% of the time the result of unequal crossing over between the X and the Y in the male during meiosis prior to gametogenesis (spermatogenesis.) In XX male syndrome, this crossover "error" has usually resulted in the SRY gene being relocated to the X rather than the Y. The X contributed by the father now comes with the SRY gene rather than on the Y where it is normally found. Thus, an individual with a female (XX) genotype has phenotypically male characteristics.

  • XY
    • condition 1 - results in normal male

      Hanna tells her story.
      condition 2 (intersex) - Androgen insensitivity syndrome (AIS). Prevents or impairs the masculinization of male genitalia in the developing genetic male (XY) fetus, as well as the development of male secondary sexual characteristics at puberty.

      The androgen receptor (AR) gene (NR4C4) is located on the X chromosome. In the case of AIS, the AR is unresponsive to testosterone. The way a normal AR works is that when exposed to testosterone, it binds to it, then translocates to the nucleus, where it binds to DNA when other cofactors are present. This complex then activates gene expression. These genes are thus androgen responsive. However, they aren't if the AR is defective, and doesn't bind testosterone or translocate!

      Of course, there is not simply one way that this regulatory system can become defective. There are many ways. Think about it.

      Interestingly, since the AR gene is located on the X, and since normal females are XX, then normal females can carry both a defective and a working AR gene and remain healthy. They have a 50% chance of passing the defective AR gene on to a male child. When that happens, AIS occurs. The genes that are regulated by the testosterone bound AR complex are found on several chromosomes.

  • True hermaphrodite - Pregnancy in a hermaphrodite with a male-predominant mosaic karyotype

  • X0 - Turner syndrome. Due to a chromosomal abnormality in which all or part of one of the X chromosomes is missing or altered. Signs and symptoms vary. Often, a short and webbed neck, low-set ears, low hairline at the back of the neck, short stature, and swollen hands and feet are seen. They typically develop menstrual periods and breasts only with hormone treatment, and are unable to have children without medical intervention. Heart defects, diabetes, and low thyroid hormone occur more frequently. Most have normal intelligence. Many have troubles with spatial visualization that may be needed for mathematics. Vision and hearing problems occur more often.

  • XXY - Klinefelter syndrome. Primary features are sterility and small testicles. Often, symptoms may be subtle. Sometimes, symptoms are more prominent and may include weaker muscles, greater height, poor coordination, less body hair, breast growth, and less interest in sex. Intelligence is usually normal. Reading difficulties and problems with speech are more common. Symptoms are typically more severe if three or more X chromosomes are present (XXXY syndrome or 49,XXXXY). XXY males are also more likely than other men to have certain health problems that typically affect females, such as autoimmune disorders, breast cancer, venous thromboembolic disease, and osteoporosis.

  • XYY - XYY syndrome. Symptoms are usually few. They may include being taller than average, acne, and an increased risk of learning problems. The person is generally otherwise normal, including normal fertility. People with the 47,XYY karyotype have an increased growth velocity from early childhood, with an average final height approximately 7 cm (3") above expected final height.

  • XXYY - XXYY syndrome. Recall that the appearance of at least one Y chromosome with a properly functioning SRY gene makes a male. Therefore, humans with XXYY are genotypically male. Males with XXYY syndrome have 48 chromosomes instead of the typical 46. Extra copies of genes on the X chromosome interfere with male sexual development, preventing the testes from functioning normally and reducing the levels of testosterone. Many genes are found only on the X or Y chromosome, but genes in areas known as the pseudoautosomal regions are present on both sex chromosomes. Extra copies of genes from the pseudoautosomal regions of the extra X and Y chromosome contribute to the signs and symptoms of 48,XXYY syndrome.

    Among the impacts: developmental delays, speech impairment, behavior outburst and mood swings, intellectual impairment, autism spectrum disorders, tall stature, scoliosis, clinodactyly, low muscle tone, sterility, delayed sexual development, undescended testes.

  • XXX - Triple X syndrome

  • XXXX - Tetrasomy X

  • XXXXX - Pentasomy X

A detailed listing of the genes, their products, and the systems in play that result in the manifestation of male and female behavioral, perceptual, instinctual, and physiological characteristics is beyond the scope of this chapter. It is also not possible given our current knowledge.

However, one example will be given, picked at random, as a peek at the complexity that is beginning to be understood regarding the genesis of sexual dimorphism. Not surprizingly, what is known does not differ in the abstract from what is known about other biological systems, their development, their regulation, and their response to the environment they find themselves within. The details differ. The complexity, although astounding, does not.

The following example does not involve the AR gene, but does involve a gene that produces a protien that interacts with AR, among other systems.

[ Protein NR5A1 pic ]
Structure of the NR5A1 protein.
Steroidogenic factor 1 (SF-1) protein is a transcription factor involved in sex determination by controlling activity of genes related to the reproductive glands or gonads and adrenal glands. Other roles in endocrine function have been discovered. This protein is encoded by the NR5A1 gene, a member of the nuclear receptor subfamily, located on the long arm of chromosome 9 at position 33.3.

Following sequence specific DNA binding, trans-activation of target genes depends on recruitment of co-activators such as SRC-1, GRIP1 (note, possible glutamate neurological receptor involvement in learning and memory), PNRC (note, a coactivator of several other nuclear receptors), or GCN5. The hinge region can undergo post-transcriptional and translational modifications that further enhance stability and transcriptional activity.

In males, SF-1 (NR5A1) transcripts precede the onset of SRY (sex-determining region Y protein) expression in the fetal testes hinting at gonadal developmental role. SRY influences the differentiation of the fetal testes into distinct compartments: testicular cords and interstitial region containing Leydig cells. Increase in SF-1 protein and detection in the steroidogenic Leydig cells and testicular cords coincides with development.

However, in females, in the ovaries, gonadal sexual differentiation is facilitated by reductions in SF-1 transcript and protein. SF-1 levels are strongly expressed at the onset of follicular development in theca and granulosa cells which precedes expression of the aromatase enzyme responsible for estrogen biosynthesis.

Other genes related to sexual dimorphism development are included in the Multfilters subsection of this section.


A Few Systems Examples that contribute to the manifestation of Sexual Dimorphism:

Each of these "Sexual Dimorphism Personality Ensembles", which altogether make up the Sexual Dimorphism Spectrum Tapestry, are themselves tapestries and ensembles of Filters or other Ensembles (such as the Humor Ensemble.)

While the Sexual Dimorphism Ensemble's activity may be independent of environmental influence (it is instinctual only, and is either active within a default phenotypic manifestation range or it is not), multiple things fall out of the fact that how it manifests itself responds to the Environment (it is adaptable):
