“…The repeatability of the result in independent crosses provides strong evidence that the observed differences were caused by the maternal genetic effect of egg size rather than by random environmental variation (Stone 1947). Note also that the egg size effect occurred independently of the covariation between the traits in the parental populations.…”

We used a novel approach to study the effects of egg size on offspring fitness components in Drosophila melanogaster. Populations that differed genetically in egg size were crossed, and the female offspring from these reciprocal crosses were examined for life-history traits. These flies expressed effects of egg size, because they developed from eggs of different sizes as a result of maternal genetic effects, but displayed an equivalent range of nuclear genetic variation. The crosses used four independent pairs of outbred populations that differed in the pattern of covariation between egg size and life-history traits, so that the maternal genetic effects of egg size on offspring characters could be contrasted to the associations present among the parental populations. Egg size showed positive maternal genetic effects on embryonic viability and development rate, hatchling weight and feeding rate, and egg-larva and egg-adult development rate but no consistent effects on larval competitive ability, adult weight, or egg size in the offspring. Our method revealed a pattern of causality that could not be deduced from interpopulation comparisons and therefore provides a good way of disentangling the causes and consequences of variation in egg size while controlling for zygotic genetic effects.

“…Neel (1941) and Sparrow and Reed (1940) reported on the interaction of mutants that affect the chaetae of D. melanogastcr. Stone (1947) used the effect of several mutants on Dichaete in an attempt to discover whether differences existed in reciprocal crosses.…”
