Evolution of DNA in Heterochromatin: the Drosophila Melanogaster Sibling Species Subgroup as a Resource

The Drosophila melanogasterspecies subgroup is a closely-knit collection of eight sibling species whose relationships are well defined. These species are too close for most evolutionary studies of euchromatic genes but are ideal to investigate the major changes that occur to DNA in heterochromatin over short periods during evolution. For example, it is not… CONTINUE READING
