Explain why the workers in a colony of eusocial bees might be expected to feed their sisters three times as much food as their brothers. (Assume all of the offspring are produced from the same male and female).

Solutions

Expert Solution

In eusocisl bees there is a high level of organisation of the society with cooperation, division of labor and brood care.
brood care involves caring of offspring from other individuals.

An organism doesn't only gain reproductive fitness by increasing their own reproductive output but it can also assist in the reading of other members of the society to increase the fitness. This comes under inclusive fitness .

Bees are haplodiploid species. It means that some individuals are diploid (females) and some are haploid (males).
the females are formed by fertilised eggs and males are formed by unfertilised eggs. This way the worker bee is more related to his sister than to his own offspring as it shares 75% of his DNA with his sister. On the other hand they only share 25% of their genes with their brothers . So , it makes more sense in tending to the care of females than males because there is better Chance of passing on their genes through them.

Parthenogenesis: In bees, males (drones) develop from unfertilized eggs ad are haploid. Females (workers and queens) are diploid and come from fertilized eggs. W (black eyes) is dominant over w (white eyes). Workers of genotype RR or Rr use wax to seal crevices in the hive; rr workers use resin instead.

In the labor market the wage rate requested by workers will generally depend on workers’ expected price Pe which is to prevail in the future, the current unemployment rate u, and a variable z that represents the unemployment benefits package. This defines the wage-setting relationship: W = PeF(u,z). At the same time, firms define the price-setting relationship: P = (1+m)W, where m is the markup of goods prices over wage rate.
