The Y chromosome is about one-third the size of the X and contains far fewer genes. Now, scientists have found that this ...

Humans inherit one set of chromosomes from their mother and a second set from their father. In total, most human cells contain 46 chromosomes with 22 pairs of autosomes, or non-sex chromosomes ...

New research funded by the National Institutes of Health has generated the first complete chromosome sequences from non-human primates. These sequences highlight variations between the Y ...

In particular, it explains that humans have one fewer chromosome pair in their cells than apes, due to a mutation found in chromosome number 2 that caused two chromosomes to fuse into one.

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 ...

It’s not clear why these backups have evolved. The new Y chromosome sequences could spell change for metagenomics research, which involves sequencing microbial genomes. Human DNA contaminants often ...
