Researchers at the Francis Crick Institute studying male mice engineered with different Y chromosome deletions have uncovered which genes on the mouse Y chromosome regulate the development of sperm ...

Humans have 23 pairs of chromosomes, including a pair of sex chromosomes (typically XX for females, and XY for males). Chromosomes contain hundreds to thousands of genes, which are sections of DNA ...

The human Y chromosome, responsible for male sex determination, has forfeited 97% of its ancestral genes over the past 300 million years. Evolutionary biologist Jenny Graves cautioned it "is running ...

Researchers at the Crick have uncovered which genes on the Y chromosome regulate the development of sperm and impact fertility in male mice. This research could help us understand why some men don't ...

This is a preview. Log in through your library . Abstract Haplodiploidy and paternal genome elimination (HD/PGE) are common in invertebrates, having evolved at least two dozen times, all from male ...

Researchers have shed new light on how a type of heart valve disease -- aortic valve stenosis -- progresses differently in males and females. A study led by bioengineers at the University of ...

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 ...

Researchers used CRISPR to change the number of chromosomes in Arabidopsis by fusing chromosome arms, reducing the genome from ten to eight chromosomes. The plants grew normally but showed reduced ...
