Horse Y Chromosome Mapped

NEW YORK, June 16 (GenomeWeb News) - Researchers have created a detailed physical map of the horse Y chromosome, presenting their results in this week's online early edition of the Proceedings of the National Academy of Sciences.


The scientists, from Texas A&M University and the University of Veterinary Medicine Vienna, found that about one third of the chromosome on the long arm consists of euchromatin, whereas the rest is predominantly heterochromatic.


According to the researchers, the map is currently the most informative among Y chromosome maps in domesticated species. It lays the foundation for sequence analysis of the horse Y chromosome, which might help understand male infertility in both horses and humans.
