When closely related species mate, their offspring sometimes survive but cannot reproduce. This pattern often affects males ...

A recent study by Fred Hutch biochemist Christopher Lapointe, PhD, and his colleagues, uses innovative lab techniques to ...

When a species lives in two distinct types of habitats, individuals with traits better suited to each habitat will thrive and ...

When a species lives in two distinct types of habitats, individuals with traits better suited to each habitat will thrive and reproduce, naturally selecting descendants with those traits. But what ...

Analysing the births of a Utah family over seven generations has revealed that their disproportionate number of boys could be caused by a selfish Y chromosome ...

Today, organisations such as Unesco, the UN body for education, science and culture, are grappling with how schools and universities can respond to rising misinformation and declining trust in ...

The Y chromosome is among the smallest in the human body and carries the fewest genes. Researchers are paying renewed attention to its role in cancer—specifically, what happens when it vanishes.

Loss of the Y chromosome in aging men is widespread and increasingly linked to serious diseases, challenging assumptions that ...

Jenny Graves receives funding from The Australian Research Council. Men tend to lose the Y chromosome from their cells as they age. But because the Y bears few genes other than for male determination, ...

The research team, led by scientists including Ryo Hashizume, worked with skin cells and induced pluripotent stem cells derived from people with Down syndrome. Rather than altering individual genes, ...

Is it possible that Y Chromosomes might actually disappear from genetic code? What would happen to species as we know them? We're generally taught that chromosomes determine an animal's sex, but turns ...
