Abstract:
:The evolutionary conservation of Y chromosomal DNA sequences of Drosophila hydei in different species of the genus Drosophila was studied by in situ hybridization and on genomic DNA blots of restriction enzyme digested DNA. We demonstrated that Y specific DNA sequences, which form major parts of lampbrush loops related to the male fertility genes, are only retained in a few closely related species during evolution. Other Y chromosomal DNA sequences, also present in lampbrush loops but with homology to autosomal and X chromosomal locations, were found in distant species. We propose a model for the evolution of the Y chromosomal lampbrush loops.
