Homolog pairing and sister chromatid cohesion in heterochromatin in Drosophila male meiosis I.

Chromosoma - 1 Aug 2011

Tsai Jui-He, Yan Rihui, McKee Bruce D

Abstract excerpt

Drosophila males undergo meiosis without recombination or chiasmata but homologous chromosomes pair and disjoin regularly. The X-Y pair utilizes a specific repeated sequence within the heterochromatic ribosomal DNA blocks as a pairing site. No pairing sites have yet been identified for the autosomes. To search for such sites, we utilized probes targeting specific heterochromatic regions to assay heterochromatin...
