Answer:
The correct answer is - c. Larger claws would help the crab crack open the shells of the mussels so the crab can eat them.
Explanation:
The graph (attached) states that the two variables size of claws of the crabs depends on the thickness of the shell of mussels. With the increase in the thickness of the shell of the mussels the size of the claws of crabs also increases and becomes larger.
The most likely explanation of this change would be adapting according to the change in the shell of the crab as they require to crack their shell to eat them as mussels are the primary food source of these crabs.

Answer:
Explanation
Given that 36% are recessive in traits
100-36 = 64% for dominant traits considering a whole population to be 100%
P=dominant allele
q= recessive allele
P2= dominant genotype
q2= recessive genotype
 according to hardyweinberg principle, p+q=1
64/100= 0.64 frequency for dominant traits or genotype, therefore 
 p2=0.64 
 then
P=√0.64
p= 0.8
Therefore, dominant allele frequency (p) for the population is 0.8
