D. females with infants are not sexually receptive

Choose the INCORRECT answer.

Answer 1

The incorrext option is A beacause Infanticide caused by sexual conflict has the general theme of the killer (often male) becoming the new sexual partner of the victim's parent, which would otherwise be unavailable. This represents a gain in fitness by the killer, and a loss in fitness by the parents of the offspring killed. This is a type of evolutionary struggle between the two sexes, in which the victim sex may have counter-adaptations that reduce the success of this practice.It  may also occur for other reasons, such as the struggle for food between females. In this case individuals may even kill closely related offspring.
