[Dynamics of changes in various adaptation components in Drosophila ontogenesis].
We studied the effect of parental age on expressivity of trait eyeless, fertility, heat resistance, and life span of Drosophila offspring. We found that these characteristics show different changes in the offspring of aging parents. The ontogenetic curve of changes of expressivity of the trait eyeless and fertility is similar to the curve of normal distribution. As concerns the changes in heat resistance, they are complex in nature: the offspring of "young" or "old" parents has the highest heat resistance. Age of parents in the studied range does not significantly affect the mean life span of the offspring.
