Meiotic double strand DNA breaks and spontaneous mutation in Drosophila melanogaster

Robert H. Melde, Austin Daigle, JoHanna M. Abraham, Nathaniel P. Sharp

This study investigates the relationship between meiotic double-strand breaks (DSBs) and mutation patterns in Drosophila melanogaster by comparing mutation accumulation in strains with and without DSBs.

Sex-specific viability effects of mutations in Drosophila melanogaster

Robert H. Melde, JoHanna M. Abraham, Maryn R. Ugolini, Madison P. Castle, Molly M. Fjalstad, Daniela M. Blumstein, Nathaniel P. Sharp

The paper measures sex-specific viability effects of mutations in Drosophila melanogaster and finds that both marker mutations and mutagenized chromosomes reduce viability in both sexes, with some sex-biased selection but not male-biased mutational variance.
