Chromosomal Sex Determination in Drosophila

WebProper segregation of chromosomes during meiosis relies on the formation of programmed double-strand breaks (DSBs), which are initiated by the evolutionarily conserved type II DNA topoisomerase-like protein Spo11 (Mei-W68 in Drosophila) (2, 3).These DSBs are then repaired as crossover or gene conversion events (Fig. 1 A and B).Crossovers mature … WebC (1)DX is popular because it is more stable than most attached-X chromosomes. The reason is that the medial heterochromatic block in C (1)DX is particularly small and, consequently, it is a smaller target for translocation events leading to detachment.
