Allozymic heterozygosity and morphological variation in house sparrows.

Nature - 1 Jan 2000

Fleischer R C, Johnston R F, Klitz W J

Abstract excerpt

Several reports have shown that greater heterozygosity (both between individuals and between populations) is associated with lower morphological variance and asymmetry. Most previous work concerned poikilothermic organisms (for example, fish, butterflies, lizards, shellfish, salamanders and plants). Reports concerning two homoiotherms gave conflicting results. The report by Handford on a songbird, Zonotrichia...
