I propose some more visual additions to this article. Currently, it is all text.

Currently, the first example of antagonistic pleiotropy is "An example of this would be female rodents that live in a nest with other females and may end up feeding young that are not theirs due to their intense parental drive. This strong parental drive will be selected for, but the organisms will still make the mistake of feeding young that are not theirs and misallocating their resources."

This mistakenly frames selection as operating primarily on the level of the individual, rather than at the level of the gene. The suite of "parental drive" genes that drive the rat to feed the offspring of other rats is not driving a misallocation of resources if the other offspring also contain the parental drive genes. Parental drive genes coexist with another suite of genes that might be "offspring privileging genes," allowing the rat to identify and protect her own offspring at the expense of those of other rats. But this is tangential.

Given that antagonistic pleiotropy arose in the context of explanations for aging/senescence, it seems best if this example were replaced with one relevant to aging. AllAmericanBreakfast ( talk) 04:04, 7 November 2022 (UTC) reply
