Gilks W. Selection for female counter-adaptations would also be more efficient than on autosomes when beneficial alleles are recessive Charlesworth et al. If this gamete is used to form a zygote, all cells in the resulting offspring will carry the abnormal chromosome number.
Sequence and comparative analysis of the chicken genome provide unique perspectives on vertebrate evolution. In: Huxley JS ed. We conclude that the link between sexual isolation and evolution of hybrid sterility is more intuitive in male-heterogametic taxa because recessive sexually antagonistic genes are expected to quickly accumulate on the X-chromosome.
His work discovered the model of X-linkage and sex inheritance. Ramneet Kaur Ramneet Kaur is professor of Biology. What is a Chromosome and its Function? Send My Free Book. See author's posts.
Sexual selection and natural selection in bird speciation.

QTL analysis of a rapidly evolving speciation phenotype in the Hawaiian cricket Laupala.
Sign up for news from real people doing interesting things in genetics, healthcare, and the science of being human. Mouse Genome Sequencing Consortium By contrast, sexually antagonistic alleles that are dominant and favour homogametic males for example, birds are expected to accumulate on Z because Z spends two times as much time in males Rice, Sex linkage and speciation in Lepidoptera.
They found that species recognition was Z-linked, as were male plumage traits and genes causing low fitness in hybrids Table 1.
