  1. We will now take a more detailed look at these events. The speculation was that a copy of this autosomal gene, introns and all, somehow made its way onto the Y chromosome and became modified and testis specific.

  2. Mammals with an XO karyotype have no testes, but their pouch and mammary glands are replaced with an empty scrotum [ 6 ].

  3. The hunt for the sex-determination loci in S. From Mating Types to Sexes Meiotic sex likely has a single origin, which dates back to the origin of eukaryotes [] , [].

  4. Moreover, other testis-forming genes have been found on the autosomes. The hybrids retained only one or two marsupial chromosomes in a background of rodent chromosomes, so it was possible to identify marsupial proteins in hybrids by isozyme typing and marsupial genes by Southern blotting.

  5. In this chapter, I describe and analyze the methods that have been and could be used for isolation of active Y-linked genes and Y-specific sequences in plants. Four genes from the human Y chromosome have now been found to map to the tiny marsupial Y chromosome and must have been on the Y chromosome for at least million years personal communication with Waters.
