Avian Sex Chromosomes and Sex-Linked Genesvian . homolog(s) argues against its role in avian sex determination. However, a recent study suggests that at least some genes associated with gonadal development are conserved among mammals and birds (Smith .., 1999).

Meiotic Chromosomes and Meiotic Mechanismsrotists cannot be safely thought as coming from asexual ancestors. It may be remarked that the asexual stercorarian trypanosomes show large variations in nuclear DNA content and “electrokaryotype” (reviewed in Solari, 1995) while protists having regular sex cycles and meiosis, as ., show a much more constant karyotype (Gardner, 1999).

Mathematical Foundations and Notation,1996; Verheijen .., 1989b). 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

It will be discussed that mammalian KU70 dsDNA end-binding protein may not play a structural role at the meiotic telomere. I will discuss a putative pathway linking the meiotic telomere to cell cycle progression, cytoskeleton and nuclear envelop

Second, the resolution of banding analysis is for obvious reasons roughly one chromosome band, and since a typical band contains millions of bases and hundreds of genes, that is a rather low r
