Question

a. Kin selection is an explanation of the evolution of male aggression. True or False

b. Mass extinctions are typically caused by competition among species. True or False

c. Alleles that are the same DNA sequence and inherited from a recent common ancestor are known by what term?

	A.	Identical by State
	B.	Identical by Descent
	C.	Alleles
	D.	Identical alleles
	E.	Outbred

Answer 1

Question

a. Kin selection is the process where individuals try to survive by producing offspring. For example bees , produce large number of offspring and worker bee help in the reproduction but are not directly involved in reproduction.  Evolution of male aggression is an example of sexual selection. Hence, it is a false statement.

b. Mass extinction are caused due to sudden change in climatic condition, massive volcanic eruption, asteroid impacts not by competition . Hence, it is a false statement.

c. Alleles that are inherited from a recent common ancestor are known as identical by descent. Hence, option B is correct.
