The ape sex chromosomes have now been fully sequenced. Rapid evolution has led to extreme differences in the Y chromosome between species, whereas the X chromosome experienced much less dynamic ...
Newly generated, complete genomes for the sex chromosomes of six primate species — produced by an international collaboration led by researchers at Penn State and the National Human Genome Research ...
The evolution of sex chromosomes influences reproductive biology and genome evolution across species. In Drosophila pseudoobscura, the Y chromosome has a distinct origin compared to Drosophila ...
In 2002, evolutionary biologist Jenny Graves shared a controversial calculation. The human Y chromosome, she wrote two years later in a commentary, "is running out of time." The male-determining sex ...
New findings challenge researchers' understanding of how the Y chromosome evolved -- rather than being the slowest component of the genome to change, as generally believed, it might just be the ...
A 3D graphic showing an artist's interpretation of human X and Y chromosomes. On the left are blue bundles of genetic material making an X shape and on the right blue bundles of genetic material ...
