Latest Y chromosome Stories
A UT Arlington research team says their study of genetic information from more than 4,000 beetle species has yielded a new theory about why some species lose their Y chromosome and others, such as humans, hang on to it.
Man or woman? Male or female? In humans and other mammals, the difference between sexes depends on one single element of the genome: the Y chromosome.
Male bears are seemingly always on the prowl, roaming much greater distances than females, particularly for mating.
A new study in PLOS Genetics has found that the human race may not be losing the Y chromosome after all.
The Y chromosome is a symbol of maleness, present only in males and encoding genes important for male reproduction. But live mouse offspring can be generated with assisted reproduction using germ cells from males with the Y chromosome contribution limited to only two genes: the testis determinant factor Sry and the spermatogonial proliferation factor Eif2s3y.
An analysis of the genealogical and medical records of males in Utah's multi-generational families strongly supports the case that inherited variations in the Y chromosome, the male sex chromosome, play a role in the development of prostate cancer.
A new method for visualising chromosomes is painting a truer picture of their shape, which is rarely like the X-shaped blob of DNA most of us are familiar with.
Biologists reported today in Nature that they have identified two pathways through which chromosomes are rearranged in mammalian cells.
New research indicates that the development of gender in human males is tenuous and could point to a biological mechanism behind a whole spectrum of gender identities.
