Latest Sex-determination system 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.
In previous research, UC Berkeley scientists Beatriz Vicoso, Ph.D., and Doris Bachtrog, Ph.D., determined that genes on the so-called "dot chromosome," or fourth chromosome, of the fruit fly Drosophilia melanogaster are X-linked in three other related fly species.
A new study in PLOS Genetics has found that the human race may not be losing the Y chromosome after all.
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.
Scientists from Zhejiang University in China and BGI Shenzhen have completed and analyzed the genomic sequence of the endangered Chinese alligator (Alligator sinensis) – the first published crocodilian genome.
The Y chromosomes of cattle have more genes and are more active than the Y chromosomes of other primates, according to researchers.
Two new studies offer insight into sex chromosome evolution by focusing on papaya, a multimillion dollar crop plant with a sexual problem (as far as growers are concerned) and a complicated past.
New findings of researchers from the University of Modena and Reggio Emilia (Mauro Mandrioli, Valentina Monti and Gian Carlo Manicardi) show that in aphids the two X chromosomes have a different inheritance.
Male mice born with female sex chromosomes experience hypertension seen in postmenopausal women
