Like us, they had two copies of 22 of those chromosomes (one from each parent), and also a pair of sex chromosomes. Females had two X chromosomes, while males had one X and one Y.

T he Y chromosome, which determines the sex of human and other mammal babies, is slowly degenerating and may disappear within a few million years, raising fears of extinction. However, a 2022 ...
