Sex Determination Mechanisms

Sex-determination mechanisms and sex chromosomes are known to vary among reptile species and, in a few celebrated examples, within populations of the same species. The oriental garden lizard, Calotes versicolor, is one of the most intriguing species in this regard, exhibiting evidence of multiple sex-determination modes within a single species. One possible explanation for this unusual distribution is that in C. versicolor, different modes of sex determination are confined to a particular population or a species within a cryptic species complex. Here, we report on a population genetic analysis using SNP data from a methylation-sensitive DArT sequencing analysis and mitochondrial DNA data obtained from samples collected from six locations: three from Bangladesh and three from Thailand. Our aim was to determine whether C. versicolor is best described as a single species with multiple lineages or as multiple species, as well as if its sex-determination mechanisms vary within or between species. We present evidence that the latter possibility is the case and that C. versicolor comprises a complex of cryptic species. We also identify sex-linked markers within these species and use them to identify modes of sex determination. Overall, our results suggest that different sex-determination modes have evolved among closely related species and within populations of Agamid lizards.

AbstractThe worldwide distribution and extensive genetic diversity of the whitefly Bemisia tabaci has long been recognized. However, whether B. tabaci is a complex species or a species complex has been a subject of debate. Recent phylogenetic analyses suggest that B. tabaci is a cryptic species complex composed of at least 24 morphologically indistinguishable species. Here, we conducted crossing experiments and demonstrated reproductive incompatibility among three of the 24 putative species. Our data and those of previously reported crossing experiments among various putative species of B. tabaci were collated to reveal the pattern of reproductive isolation. The combined results provide strong support to the proposition that B. tabaci is a cryptic species complex.
