Researchers led by UC Davis Health scientist Sanchita Bhatnagar have developed a promising gene therapy that could treat Rett ...

Biological females inherit two X chromosomes—one from each parent—along with all the other genetic material that builds and sustains the body.

The most common form of color blindness is red-green color blindness. This happens when people are born without the type of ...

Fragile X disorders include two distinct conditions: fragile X syndrome (the most common single-gene cause of developmental ...

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.

Now researchers are working to nail down why (Getty Images/iStock) Looking inside the body, while women have two “X” chromosomes, men have an “X” and a “Y.” Chromosomes are thread-like structures of ...

But if there is just one X chromosome, as is the case with most male cells, neither the X nor the Y needs to be turned off. In some cancer cells, however, this rule is broken.

X chromosomes, some researchers hypothesize, could help explain sex differences in cognition, verbal memory or brain disease risk. “Given the fact that the X chromosome is enriched for brain-related ...

The X chromosome is silenced in some male cancers Date: November 9, 2022 Source: Cell Press Summary: Cancer cells acquire genetic anomalies that allow them to grow and proliferate unchecked.

X-chromosome inactivation varies across different areas of brains. Here, fluorescent imaging data from a mouse reveal where the father’s X chromosome is most active (white) and least active ...

For example, the X chromosomes of humans and chimpanzees are about 98 percent identical in makeup. On the other hand, only about one-third of the Y chromosomes of the two species matched.

When the Y chromosome was discovered about 15 years later, researchers just continued on with the alphabet. All chromosomes have roughly the same shape, but the Y chromosome is smaller in size — about ...
