Sexual selection can partly explain low frequencies of Segregation Distorter alleles.

Proceedings. Biological sciences - 29 Sept 2021

Keaney Thomas A, Jones Therésa M, Holman Luke

Abstract excerpt

The Segregation Distorter (SD) allele found in Drosophila melanogaster distorts Mendelian inheritance in heterozygous males by causing developmental failure of non-SD spermatids, such that greater than 90% of the surviving sperm carry SD. This within-individual advantage should cause SD to fix, and yet SD is typically rare in wild populations. Here, we explore whether this paradox can be resolved by sexual...
