| g-band patterns of the siberian snow sheep (ovis nivicola) and their relationship to chromosomal evolution in sheep. | g-band patterns of the siberian snow sheep, ovis nivicola alleni, 2n=52, were compared with the patterns reported in 2n=54 wild asiatic mouflon and 2n=54 north american sheep and those in domestic sheep with 2n=54, 53, and 52. the three largest pairs of biarmed autosomes displayed indistinguishable, presumably homologous, g-banding patterns in all types of sheep. the banding and morphology of the fourth pair of biarmed autosomes in o.nivicola differed from those of the three translocation varian ... | 1977 | 908200 |
