Understanding bulls' gene-rich Y chromosomes may improve herd fertility

Researchers including Huck Institutes affiliate Wansheng Liu have found that, surprisingly, the Y chromosomes of cattle have more genes and are more active than the Y chromosomes of a variety of primates and other mammals.

According to Liu – an associate professor of animal genomics at Penn State and a faculty member of the Huck Institutes' Bioinformatics and Genomics and Genetics graduate programs – this discovery may help biologists better understand how cattle and other mammals evolved, and also help animal breeders and farmers better maintain and enhance fertility in the cattle industry.
