Question

Kin Selection Eusociality (1.5 pts. each) Leaf cutter ants exhibit eusociality or true social behavior. Worker ants, which are females, cut and transport the leaves and rear the fungus on the leaves as well as rear the young produced by the queen. The ants exhibit baploidiploidy so all of the males have a_number of chromosomes in their body cells. The daughters from a single male receive all of the same paternal genes so the daughters are related by this source alone. Daughters ge1% of their genes from their mother. Therefore, the workers (daughters) are related by the workers from a single male and queen is % (coefficient of relatedness-r) from %(r) through their mother and the total relatedness (r) of

Explanation / Answer

the ants exhibit haplodiploidy so all of the males have a haploid number of chromosomes in their body cells. the daughters from a single male receive all of the same paternal genes so the daughters are related by 100% from this source alone. daughters get 1/2 of their genes from their mother. therefore, the workers are related by 50 % through their mother and the total relatedness of the workers from a single male and queen is 75% .
