Fine-scale genetic mapping of a hybrid sterility factor between Drosophila simulans and D. mauritiana: the varied and elusive functions of "speciation genes"
Araripe, Luciana Ordunha; Montenegro, Horácio; Lemos, Bernardo; Hartl, Daniel L. (BioMed Central, 2010)Background: Hybrid male sterility (HMS) is a usual outcome of hybridization between closely related animal species. It arises because interactions between alleles that are functional within one species may be disrupted in ... -
A Sex-Ratio Meiotic Drive System in Drosophila Simulans. I: An Autosomal Suppressor
Tao, Yun; Masly, John P; Araripe, Luciana Ordunha; Ke, Yeyan; Hartl, Daniel L. (Public Library of Science, 2007)Sex ratio distortion (sex-ratio for short) has been reported in numerous species such as Drosophila, where distortion can readily be detected in experimental crosses, but the molecular mechanisms remain elusive. Here we ... -
A sex-ratio Meiotic Drive System in Drosophila simulans. II: An X-linked Distorter
Tao, Yun; Kingan, Sarah B; Ke, Yeyan; Xiao, Hailian; Barbash, Daniel; Araripe, Luciana Ordunha; Hartl, Daniel L. (Public Library of Science, 2007)The evolution of heteromorphic sex chromosomes creates a genetic condition favoring the invasion of sex-ratio meiotic drive elements, resulting in the biased transmission of one sex chromosome over the other, in violation ...
