Polyandry is a good strategy for females because
A) mating with multiple males increases the genetic diversity of their offspring.
B) mating with more distantly related males reduces the chances of inbreeding depression in their offspring.
C) resisting courtship overtures may come at a higher cost than mating multiple times.
D) all of the above
Polyandry
A mating system in which a female has multiple male mates at the same time.
Genetic Diversity
The variety of genetic information present within species, populations, or individuals, crucial for adaptation, survival, and resistance to diseases.
Inbreeding Depression
A reduction in the average fitness of inbred individuals relative to that of outbred individuals. It arises because rare recessive alleles become expressed in a homozygous state where they can affect detrimentally the performance of individuals.
- Ascertain the divergences among assorted mating configurations (polygyny, polyandry, monogamy) and their influence on evolutionary development.

Final Answer :
D
Explanation :
Polyandry, the practice of a female mating with multiple males, can increase genetic diversity, reduce inbreeding depression, and sometimes be less costly than resisting multiple courtship attempts, benefiting the offspring and the female's reproductive success.
