Without recombination, Y chromosomal genes degenerate over ... A 2017 study published in the journal PLOS Genetics said the chromosome's evolution of palindromes — DNA sequences that read ...

The Y chromosome has seen significant changes over the course of human evolution. "In comparison to the X, the Y is tiny. There are only 45 genes on the Y chromosome, and it is just one of these ...

A tangible timekeeper of history, the Y chromosome allows us to trace human evolution, track migration patterns and relatedness in groups of people, and answer paternity questions going back ...

While the Y chromosome's shrinkage is a fascinating aspect of evolution, it is not an immediate concern. Male health and fertility remain largely unaffected for the foreseeable future.

Scientists published a full genetic sequence of the genes that make some white campions male, and hope their work could ...

A study conducted by a research team at the Crick Institute identified important genes on the Y chromosome that regulate ...

The X and Y chromosomes, commonly referred to as the sex chromosomes, are one such pair. They determine the biological sex, reproductive organs, and sexual characteristics that develop in a person.

The octopus just revealed another one of its secrets: what determines its sex. University of Oregon researchers have ...

Researchers have uncovered which genes on the Y chromosome regulate the development of sperm and impact fertility in male mice. This research could help us understand why some men don't produce enough ...

The paper B.A. Sandkam et al., “Extreme Y chromosome polymorphism corresponds to five male reproductive morphs of a freshwater fish,” Nat Eco Evol, 5:939–48, 2021. One of the key stages in the ...

When Nettie Steven discovered the Y chromosome in 1905 while studying the mealworm Tenebrio molitor, she identified it as a sex-determining chromosome. As it turns out, the chromosome also has ...
