Mitotic recombination in the heterochromatin of the sex chromosomes of Drosophila melanogaster

Mitotic recombination in the heterochromatin of the sex chromosomes of Drosophila melanogaster

P Ripoll et al. Genetics. 1978 Sep.

Abstract

The frequency of spontaneous and X-ray-induced mitotic recombination involving the Y chromosome has been studied in individuals with a marked Y chromosome arm and different XY compound chromosomes. The genotypes used include X chromosomes with different amounts of X heterochromatin and either or both arms of the Y chromosome attached to either side of the centromere. Individuals with two Y chromosomes have also been studied. The results show that the bulk of mitotic recombination takes place between homologous regions.
