Men can rest easy - sex chromosomes are here to stay

r breeds. At the same time, relaxed female selection in the fighting and plumage breeds has led to a loss of W gene expression.

This means that female-specific selection related to fertility acts to shape the W chromosome, and that the chromosome is able to respond to that selection despite all the problems with the lack of recombination.

Professor Mank said: "We have shown that Y and W chromosomes are very important in fertility the Y in males and the W in females. It is the ability of the W-linked genes to evolve that is the key to their survival, and which suggests that both the Y and the W chromosomes are with us for the long haul."
