However, there is some evidence that the Y chromosome is being phased out of the evolutionary pipeline, and could one day disappear altogether — potentially giving rise to a new sex gene in the ...

When we see pictures of chromosomes, this is usually what we ... scientists can identify a chromosome based solely on its banding pattern. Genes determine whether you have brown eyes or blue ...

In a recent study, scientists have developed a revolutionary chromosome identification system for alfalfa, one of the world's ...

Researchers have shed new light on how a type of heart valve disease—aortic valve stenosis—progresses differently in males and females. The research paves the way for treatments that can be tailored ...

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 important thing to realize about linkage is that it helps researchers identify the locations on chromosomes at which specific genes exist. Indeed, linkage is critical for mapping and ...

The silencing of the one X chromosome in XX cells is mediated by XIST, a long noncoding RNA that is randomly transcribed from only one X early in development. It coats the DNA and shuts down gene ...

The nucleus of each human body cell contains 46 chromosomes. Each chromosome contains about 1000 genes. There is enough DNA in all the cells in a human body to stretch to the sun and back again ...

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 ...
