Why is haplodiploidy thought to predispose hymenopteran lineages to eusocial behavior?
A) Daughters have a higher r than in diploid species.
B) Females have higher inclusive fitness from helping mothers than from reproducing.
C) Sisters are more closely related to each other than to their own offspring.
D) b and c
E) a, b, and c
Haplodiploidy
A mechanism through which sex is determined by the number of copies of each chromosome that an individual receives. Offspring formed from the fertilization of an egg by a sperm (that is, diploids) are female; those formed from unfertilized eggs (that is, haploids) are male.
Eusocial Behavior
The highest level of social organization, characterized by cooperative brood care, division of labor, and overlapping generations within a colony of animals.
Inclusive Fitness
Describes an individual’s combined fitness, including its own reproduction as well as any increase in the reproduction of its relatives due specifically to its own actions.
