OPTIONS:
-The fitness of offspring raised by one parent is high.
-Acquiring additional mates is relatively easy.
-Females give birth to multiple infants at once.
-Females are widely separated in an environment
Answer:
-The fitness of offspring raised by one parent is high.
-Acquiring additional mates is relatively easy.
Explanation:
When the fitness of offspring raised by one parent is high, that is if the survival and fitness of an offspring is largely favored when cared for by one parent, this might result to unequal parental investment being favored, since the survival of the offspring is mostly determined by one of the parents. For example, if breast milk and warmth of a female animal is very paramount or the survival of an offspring, there is likely going to be an unequal parental investment, since most of the caring would come from the female.
Unequal parental investment can also be favored when having access to additional mates is relatively easy.For example, if a male animal species is surrounded by many females of the same species, mating with multiple mates become easy, and when this occurs, it is very unlikely that the male would contribute anything to raising any offspring of any particular female mate, as he would just simply find it easy to move along with another female.
