What do you already know about the genetic basis of kin selection? What other information is related to the question?
Kin selection occurs when an animal does things that increase the fitness of relatives, these behaviors may even put the animal at increased risk of danger. The most important thing is to be able to recognize your kin for unrelated individuals. Genes that promote the recognition of kin are going to be very useful for promoting kin selection.

Given what you now know, what information is most likely to produce the correct answer?
Of the choices, MHC genes are the most useful in kin selection.
Reflection on Process:
Did your problem-solving process lead you to the correct answer? If not, where did the process break down or lead you astray? How can you revise your approach to produce a more desirable result?
Did you get the question right? The key to this question is to understand the concept of kin selection and how genes can influence it.
