Male-benefit sexually antagonistic genotypes show elevated vulnerability to inbreeding.

This revealed a highly significant correlation for male fitness between the old and new estimates ( r = 0.80, n = 10, P < 0.001), demonstrating that this population does indeed exhibit significant genetic variance for male fitness.

Also, genotypes encoding low fitness in both sexes exhibited greater rates of extinction relative to generally high-fitness genotypes (though marginally non-significant), an expected finding attributable to variation in mutation load across genotypes.
