On the Occurrence of Translocations and Autosomal Non-Disjunction in Drosophila melanogaster

Stern, Curt

Abstract

1. No translocations between chromosomes I, II and III of Drosophila melanogaster were found in more than 900 eggs from triploid females and the equal number of spermatozoa from diploid males. 2. Non-disjunction of the autosomes in males, resulting in spermatozoa with two or none of a special pair of autosomes was frequent. 3. Triploid females frequently produced eggs which did not receive any of the chromosomes II or III.
