TRANSGENDER AGENDA FAIL: Scientists Say There Are More Than 6,500 Genes That Express Differently In Men And Women
“Weizmann Institute of Science researchers recently uncovered thousands of human genes that are expressed — copied out to make proteins — differently in the two sexes,” notes the Weizmann Institute. The study focuses on how “harmful mutations in these particular genes tend to accumulate in the population in relatively high frequencies.”
Professor Shmuel Pietrokovski and Dr. Moran Gershoni, both researches from the Weizmann Institute’s Molecular Genetics Department, “looked closely at around 20,000 protein-coding genes, sorting them by sex and searching for differences in expression in each tissue. They eventually identified around 6,500 genes with activity that was biased toward one sex or the other in at least one tissue. For example, they found genes that were highly expressed in the skin of men relative to that in women’s skin, and they realized that these were related to the growth of body hair. Gene expression for muscle building was higher in men; that for fat storage was higher in women,” reports Weizmann Institute.
And the differences continue: mutations expressed in men were less likely to be weeded out via natural selection than in women. “The more a gene was specific to one sex, the less selection we saw on the gene. And one more difference: This selection was even weaker with men,” said Gershoni.
The researches highlighted sexual evolution theory from the 1930’s to account for such a difference: “In many species, females can produce only a limited number of offspring while males can, theoretically, father many more; so the species’ survival will depend on more viable females in the population than males,” said Pietrokovski. “Thus natural selection can be more ‘lax’ with the genes that are only harmful to males.”
There were also discoveries of sex-linked genes in the mammary glands:
Aside from the sexual organs, the researchers discovered quite a few sex-linked genes in the mammary glands — not so surprising, except that about half of these genes were expressed in men. Because men have fully fitted but basically nonfunctional mammary equipment, the scientists made an educated guess that some of these genes might suppress lactation.
While such a difference might be obvious in the mammary glands, the researchers also found genes “to be expressed only in the left ventricle of the heart in women. One of these genes, which is also related to calcium uptake, showed very high expression levels in younger women that sharply decreased with age; the scientists think that they are active in women up to menopause, protecting their hearts, but leading to heart disease and osteoporosis in later years when the gene expression is shut down.”
Additionally, they found “another gene that was mainly expressed in women was active in the brain, and though its exact function is unknown, the scientists think it may protect the neurons from Parkinson’s — a disease that has a higher prevalence and earlier onset in men. The researchers also identified gene expression in the liver in women that regulates drug metabolism, providing molecular evidence for the known difference in drug processing between women and men.”
“The basic genome is nearly the same in all of us, but it is utilized differently across the body and among individuals,” said Gershoni. “Thus, when it comes to the differences between the sexes, we see that evolution often works on the level of gene expression.”
“Paradoxically, sex-linked genes are those in which harmful mutations are more likely to be passed down, including those that impair fertility. From this vantage point, men and women undergo different selection pressures and, at least to some extent, human evolution should be viewed as co-evolution. But the study also emphasizes the need for a better understanding of the differences between men and women in the genes that cause disease or respond to treatments,” added Pietrokovski.
Still, the many intricate biological differences between men and women, such as the ones expressed by Weizmann Institute researchers, will be said by progressives to be simply overridden by one’s feelings.
