Abstract The heritability of resistance to death from the effects of lead in laboratory guppy populations was determined from comparisons between progeny produced in a nested breeding experiment and from
mass selection experiments. Resistance was measured by the time to death. Heritabilities of resistance to lead were estimated to be 0.26 and 0.57 from comparisons of progeny resistance. Realized heritability estimates ranged from 0.28 to 0.68. Uptake studies following exposure of guppies to lead contaminated solutions showed that greater amounts of lead were concentrated
in the head region than in other body tissues. Uptake rates were greater in lead resistant groups than in control groups.
