Science 40— Genetics— Investigations of Y chromosome rearrangements identified six fertility factors on the Drosophila Y 2223and several of these fertility factors span several mega-bases of DNA, and are over times larger than the average Drosophila gene In addition, detailed molecular and bioinformatics analyses have allowed identification of most of the protein-coding genes located on the completely heterochromatic Y chromosome of Drosophila melanogaster 22 - 30but the vast majority of non-exonic DNA on the Drosophila Y has not been sequenced Box 2.

We estimated time since transposition based on the number of substitutions between the two LTR arms [ 71 ]. Google Scholar Crossref.
