PARENTAL INVESTMENT

the quantity of energy a mother or father uses in caring for their young. Since ova are much bigger than sperm, and female mammals go through gestation and then lactation, it is frequently presumed that female mammals have more than males.

PARENTAL INVESTMENT: "Parental investments are said to often be greater for mothers than fathers, but it would be more politically correct to say they're greater for the primary caregiver, as times are changing."
