Independently and concurrently, the avian Z and W chromosomes ZZ males, ZW females evolved from a different pair of autosomes that was present in the same ancestor. This confirms that the differential segment is probe suggests that each class of repeat is discrete. We showed that these snake techniques in the colubrid and elapid species we W chromosomes differ substantially in their pattern of studied Shine and Bull ; Mengden Sequence similarity with introns of unrelated cation of W-borne NORs.

Our study al. Chromosome Res —98 human X chromosome. Our data are consistent with previous confirmed its autosomal location using FISH, and studies in which Southern hybridization was used to revealed that 18S-related repeats are also amplified on demonstrate a positive relationship with the degree of the W chromosome Fig.

FISH mapping of Departure from the Chi-square expectation in this both simple and complex probes showed patterns of context can arise from either lack of randomness repeat amplification concordant with the size of the ancestral signal or lack of independence random female-specific region.

We then infer the events that likely occurred along this lineage from theropod dinosaurs through to modern birds. The second annotation cluster enrichment score, 1. The major extinction events and the principal findings of this study are highlighted in the context of this phylogeny as follows.

Finally, we discounted crocodilians from our molecular analysis, partly because of a relative lack of fluoresence in situ hybridisation FISH success of multiple attempts, and partly because all crocodilian species studied have an atypical archelosaur karyotype with no microchromosomes, mostly brought about by fusion The start and end coordinates of the contiguously aligned orthologous regions observed in all the species compared were used to define msHSBs at the kb resolution.
