DNA sequences encoding 2 genes that are sex determining on the Z and W chromosomes of birds as well as nucleic acid fragments, proteins, polypeptides, antibodies and related products are provided

摘要

The application provides for DNA sequences (introns and exons) encoding two genes located on the Z and W chromosomes of birds (the avian CHD gene). These genes can be used to identify the sex of most birds (Class Aves) . In addition, the genes control the sex of the birds, a genetic process which is initiated as an embryo. Nucleic acid fragments, proteins, polypeptides, antibodies and related products and their use in medicine and agriculture are provided. The DNA sequences may be used in sex identification or for controlling the sex of adults or the progeny of commercially important animals.
