The mechanism of secondary nondisjunction in Drosophila melanogaster females.

Genetics - 1 Sept 2006

Xiang Youbin, Hawley R Scott

Abstract excerpt

Bridges (1916) observed that X chromosome nondisjunction was much more frequent in XXY females than it was in genetically normal XX females. In addition, virtually all cases of X nondisjunction in XXY females were due to XX <--> Y segregational events in oocytes in which the two X chromosomes had failed to undergo crossing over. He referred to these XX <--> Y segregation events as "secondary nondisjunction."...
