We observed complete interference for both oogenesis and spermatogenesis in hermaphrodite animals and for the entire lengths of both an autosome and the X chromosome. |
The degeneration cycle may be reset by formation of neo sex chromosomes by fusion between a sex chromosome and an autosome. |
The autosome that became X and Y in mammals lives on as autosomes in chickens. |
It is apparently formed by the arms of the loops becoming twisted around each other, and, as in the Acrididae, each of these arms no doubt represents a univalent autosome. |
Actually, when the STR loci in question are on an autosome as most are, then a human DNA sample will have two loci copies, so two PCR products will be amplified. |
The six largest pairs of autosomes and autosome 20 were biarmed, and the rest were acrocentric. |
