2] ([female]) sex-chromosome determining mechanism, a second centric fusion took place between the neo-Y and an acrocentric autosome Bl (of the B1B2 autosomic pair from the standard karyotype) of a B1B2 autosome pair; this occurred in such a way that the Y turned metacentric, while the unfused B2 autosome behaved as an acrocentric [X.
