During mitosis pKi-67 seems to be a constituent of a perichromosomal layer (Gautier .., 1992; Verheijen .., 1989a). Data on expression and location of pKi-67 during the meiotic divisions are scarce. Wrobel .. (1996) reported on the expression of pKi-67 in the seminiferous

Given the very distinct nature of mammalian and avian sex chromosomes, the sex determination pathway in birds is unlikely to resemble that in mammals, where the presence of the . gene product exc

The genetic scenarios how sex can be determined are of extraordinary diversity and have provoked questions on the evolution and maintenance of bisexuality. One of the unsolved problem is,

It is characterized by its bipartite structure and function. It is flanked by pseudoautosomal regions at the distal short arm (PAR1) and distal long arm (PAR2), the sequences o
