Abstract:
:Very few of the middle repetitive DNA sequences found in Drosophila melanogaster are present in all of the species of the D. melanogaster subgroup. One member of the subgroup, D. erecta, lacks most of the families of repetitive elements from D. melanogaster (including copia and 412) but possesses many other families not present in the D. melanogaster genome. Other species in the subgroup possess some families in these two species and lack others. From this we conclude that most individual middle repetitive families are highly unstable components of the Drosophila genome over short periods of evolutionary time.
