Judith D. Toms, Lori S. Eggert, Wayne J. Arendt and John Faaborg A genetic polymorphism in the sex-linked ATP5A1 gene is associated with individual fitness in Ovenbirds (Seiurus aurocapilla) Ecology and Evolution 2
We found a genetic polymorphism in the ATP5A1 gene in 38% of individual Ovenbirds. Males that had one or more copies of this allele had higher relative body mass (mass corrected for size) than other genotypes. This study is the first to link polymorphisms in the sex-linked ATP5A1 gene with fitness effects.
