What is parental manipulation? Describe various ways in which parents manipulate their progeny.

Parental manipulation is a phenomenon in animal behavior where parents influence the development, behavior, or survival of their offspring to enhance their own reproductive fitness, often at the cost of the offspring’s individual well-being. This strategy is rooted in evolutionary biology, where parents optimize their genetic legacy by selectively allocating resources and controlling offspring behavior. While parental investment is often seen as a means to enhance offspring survival, parental manipulation highlights cases where this investment is skewed in favor of maximizing parental fitness rather than that of the individual offspring.
