Each chromosome holds genes that, when “switched on,” produce proteins to do work inside of cells. You might expect that women, with two copies of X, would make twice as many X proteins as men do.

By virtue of having a second X chromosome, women get two “doses” of a protective protein from a gene that only exists on this female sex chromosome. Some people, both male and female, have an ...

Female biology – two X chromosomes and ovaries – extends life and protects mice from aging. Dec 18, 2018. Blood factor can turn back time in the aging brain. Aug 16, 2023.

In female mammals, one of the two X chromosomes is inactivated. Thanks to research using special stem cells, geneticists have been able to provide detailed insight into the molecular mechanism ...

Durham, N.C. – The first comprehensive survey of gene activity in the X chromosomes of women has revealed an unexpected level of variation among individuals, according to new work by researchers ...

Women born with a rare condition that gives them a Y chromosome don't only look like women physically, they also have the same brain responses to visual sexual stimuli, a new study shows.

Women born with a rare condition that gives them a Y chromosome don't only look like women physically, they also have the same brain responses to visual sexual stimuli, a new study shows.

And women’s chromosomes had fewer recombination points than expected. About 5 percent of the chromosome 21 pairs the researchers examined had no evidence of recombination.

Old female mice had more PLP1 in the hippocampus than old male mice, suggesting that the extra PLP1 from the second X chromosome had made a difference. To test whether PLP1 could explain the ...
