Male stalk-eyed fly.
The image depicts a male Teleopsis dalmanni perched on a rootlet at night. Members of this species form aggregations which typically contain multiple females and a single large male. At some sites in peninsular Malaysia, 30% of males carry a driving X chromosome that exhibits segregation distortion during spermatogenesis such that functional sperm typically lack Y chromosomes. Hence, they produce predominantly female offspring. Comparison of gene expression in testes from drive and nondrive males reveals hundreds of genes, most of which are on the X, that differ in expression and show greater sequence divergence than other genes. See Reinhardt et al.
