A selective advantage may have led the modern human Y chromosome to sweep through the Neanderthal population after it was introduced via interbreeding more than 100,000 years ago.

As male Drosophila grow old, selfish genetic elements that are abundant on the Y chromosome become more active, which appears to reduce longevity.

Using DNA data, researchers track family dynamics in Europe over the last 500 years and find socioeconomic status is related to married women having a child with a man other than their husband.

Multiple DNA breaks at either the centromere or the long arm of the mouse Y chromosome cause it to fragment and disappear.

In-depth analysis of the Neanderthal Y chromosome offers insights into the ancient hominins’ split with modern humans.

Increasing the expression of two genes from non-Y chromosomes restores spermatogenesis in male mice that lack Y chromosomes.

Mammalian Y chromosome genes with important functions are transferred to autosomal chromosomes more often than previously thought, a study shows.

A toothpick and a bit of chance shaped David Page’s career, which he has dedicated to understanding the mammalian Y chromosome and fetal germ cell development.

In 2014, new research findings and guidelines brought increased attention to biological differences between males and females.

A new study reveals an association between smoking and rates of Y chromosome loss in blood cells, which may explain elevated cancer risk among male smokers.

A detailed analysis of sex chromosomes finds unexpected evolution of functional Y chromosome genes across species.

Chilly mice develop more tumors; gut bacteria aid cancer treatment; two Y chromosome genes sufficient for assisted reproduction; HIV’s “invisibility cloak”

Two genes from the Y chromosome are sufficient to generate male mice capable of fathering healthy offspring via an assisted reproductive technique.

Two genomic studies place the divergence of men from their most recent common ancestor nearer in time to that of women, though the field is far from a consensus.

Researchers read the marks of intense warfare and conquest in the genes of ancient native North Americans.
