Changes in brain connectivity before and after puberty may explain why some children with a rare genetic disorder have a ...
In evolutionary terms, fitness is defined as an organism's ability to survive and reproduce its genes into the next ...
“It’s just an extra chromosome; we are not different,” she said, reinforcing the importance of awareness and acceptance.
Female (XX) mammals inherit one X chromosome from each parent, but males (XY) receive an X from their mother and a Y sex chromosome from their father. X and Y chromosomes determine not only the ...
The sports world is abuzz with the recent announcement by World Athletics regarding the introduction of chromosome testing for female athletes. This decision, aimed at maintaining the integrity of ...
Females have one active X chromosome and one dormant X chromosome in each cell. But a study suggests that genes on the dormant X get "reawakened" later in life, potentially giving the brain a boost.
The research reveals that this sex-based difference can be traced to a gene on the Y chromosome. The discovery, published in Science Advances, not only showcases the critical need to understand ...
Dormant genes on the X chromosome may reawaken in old age, potentially giving the aging female brain a boost that the male brain doesn't receive. This phenomenon may help to explain why ...
The planned changes include reinstating a version of chromosome testing that was discontinued in the 1990s, requiring ...
The reason female brains have less cognitive aging may be due to the reawakening of the dormant X chromosome late in life, which turns on genes that help sustain healthy brain cell connections.
