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 ...

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 ...

Accordingly, their position influences how their activity changes with the growth rate. Are genes distributed randomly along ...

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.

Females (XX) carry twice as many X-linked genes on their sex chromosomes as males (XY). How do cells control gene expression to manage this potentially lethal dosage problem? A prime example of X ...

When X-linked genes evade silencing on the “inactive” chromosome in XX cells, some protect women from diseases such as cancer, but others seem to promote conditions such as autoimmunity. Amber Dance ...
