How does the disposable soma hypothesis account for the abundance of alleles that show antagonistic pleiotropy with respect to age?

Question

Quizplus · Accepted Answer

The disposable soma hypothesis suggests that there is a trade-off between investing resources in reproduction or repair that favors the former during the early reproductive years and the latter during ages later in life. This trade-off gives rise to alleles that show antagonistic pleiotropy, meaning that they have contrasting effects on traits related to different stages of life. Thus, this hypothesis explains the abundance of alleles that have antagonistic pleiotropy with respect to age.
