"Mammals, such as humans, have females with two X chromosomes and males with one X chromosome and one Y chromosome, which creates an imbalance between the sexes," says lead author Dr. Nicholas ...

Geneticists have uncovered new insights into how sex chromosome systems work in the platypus and the chicken — which will lead to better understanding of our own sex chromosome evolution and gene ...

These testes-genes make up around a sixty of the Z chromosome and 1% of the chicken’s entire genome! This is particularly surprising because the Z chromosome is present twice in male birds, but the X ...

In humans, two chromosomes – X and Y – determine whether we are male or female. Of the two, Y tends to get more attention because of its small, degenerate size. Both X and Y probably evolved ...
