Cytogenetic Insights into the Evolution of Chromosomes and Sex Determination Reveal Striking Homology of Turtle Sex Chromosomes to Amphibian Autosomes.

abstract：:Twelve weeks after repeated spontaneous mating between a Bentheimer Landschaf ram and a West African dwarf doe was observed, the doe aborted a dead fetus. The aim of this study was to verify the parentage and the species of the supposed parents and the hybrid status of the fetus, using cytogenetic and molecular geneti...
