| two genomic regions together cause dark abdominal pigmentation in drosophila tenebrosa. | pigmentation is a rapidly evolving trait that is under both natural and sexual selection in many organisms. in the quinaria group of drosophila, nearly all of the 30 species have an abdomen that is light in color with distinct markings; d. tenebrosa is the exception in that it has a completely melanic abdomen with no visible markings. in this study, we use a combination of quantitative genetic and candidate gene approaches to investigate the genetic basis of abdominal pigmentation in d. tenebros ... | 2014 | 24326291 |
