The Coefficient of Relatedness (R) is a Measure Of

Question

The coefficient of relatedness (r) is a measure of
A) each individual's fitness benefits.
B) the probability that two individuals acquire the same allele through descent from a common ancestor.
C) the probability that two randomly chosen individuals share the same genetic trait.
D) parental investment.

Accepted Answer

The coefficient of relatedness (r) is a measure of the probability that two individuals share the same allele through descent from a common ancestor. It is used to assess the degree of relatedness between individuals in a population, which is important for understanding the evolution of certain traits and for predicting the spread of genetic diseases. A and D are not correct because they are not directly related to the coefficient of relatedness, and C is partially correct but not the best answer as it only describes the probability of sharing a specific genetic trait rather than the overall genetic relatedness.
