A Deficiency Screen of the Major Autosomes Identifies a Gene (<i>matrimony</i>) That Is Haplo-insufficient for Achiasmate Segregation in Drosophila Oocytes

Abstract excerpt

In Drosophila oocytes, euchromatic homolog-homolog associations are released at the end of pachytene, while heterochromatic pairings persist until metaphase I. A screen of 123 autosomal deficiencies for dominant effects on achiasmate chromosome segregation has identified a single gene that is haplo-insufficient for homologous achiasmate segregation and whose product may be required for the maintenance of such...
