Meiotic drive. Molecular phylogram depicting the relationships among genera of bats in the subfamily Phyllostominae highlighted in bold and the divergence time estimates node ages from BEAST analysis of all genes. Rates of fixation of chromosomal change R to be incorporated in this method were estimated using the size-corrected average generation length data estimated by Pacifici et al.

Evolution in the genus Drosophila. An advantage for the evolution of male haploidy and systems with similar genetic transmission. Abbott JK. We used multiple approaches to investigate the dynamics of chromosomal evolution in lineages of bats with considerable karyotypic variation, focusing on the different facets contributing to fixation of the exceptional chromosomal changes in Tonatia saurophila.

  • Apr 21,  · Many sex chromosomes follow this model and descend from a pair of once homologous autosomes. The theory of sex chromosome evolution implies a successive expansion and decay of the region surrounding the sex-determining locus, with an inevitable progression from homomorphic to heteromorphic sex chromosomes. For this to happen, the location Cited by: 6. Jun 02,  · The generally accepted model for sex chromosome evolution goes like this: 1) A genetic variant arises on an autosome (a non-sex chromosome) and specifies either the male or female Casey Mcgrath.
