Drosophila ribosomal RNA genes function as an X-Y pairing site during male meiosis.

Cell - 6 Apr 1990

McKee B D, Karpen G H

Abstract excerpt

In Drosophila melanogaster males, the sex chromosomes pair during meiosis in the centric X heterochromatin and at the base of the short arm of the Y (YS), in the vicinity of the nucleolus organizers. X chromosomes deficient for the pairing region segregate randomly from the Y. In this report we show that a single ribosomal RNA (rRNA) gene stimulates X-Y pairing and disjunction when inserted onto a...
