Rapid suppression of drive for a parasitic B chromosome.
Cytogenet Genome Res. 2004; 106(2-4):338-43.CG

Abstract

The persistence of parasitic B chromosomes in natural populations depends on both B ability to drive and host response to counteracting it. In the grasshopper Eyprepocnemis plorans, the B24 chromosome is the most widespread B chromosome variant in the Torrox area (Málaga, Spain). Its evolutionary success, replacing its ancestral neutralized B variant, B2, was based on meiotic drive in females, as we showed in a sample caught in 1992. In females collected six years later, mean B24 transmission ratio (k(B)) was 0.523, implying a very rapid decrease from the 0.696 observed in 1992. This shows that B24 neutralization is running very fast and suggests that it might most likely be based on a single gene of major effect.
