Question
I already know how to do A and B can anyone help me with C and D, thank you.
In a study of the codominant blood typing alleles, LM and LN in a population of mice on Island A, it was found that there were 165 MM blood types 870 MN and 965 NN blood types.
A. (2 points) Give the values for p and q in this population, showing your calculations.
B. (2 points) Is the population in Hardy-Weinberg equilibrium? How do you know? A neighbouring population on Island B, has LM frequency = 0.8 and LN = 0.2.
C. The two populations have never “met” before, but then 200 mice from population B travel to island A by accident on a floating raft of logs and plant material. What will the allele frequencies in this new merged population be? (2 points)
D. Suppose that positive assortative mating takes place in this new population and mice now only mate with mice of the same MN blood type as themselves. What will the allele frequencies be after one generation of this assortative mating? (3 points)
Explanation / Answer
A)
p = f (L M) = (2n L M L M ) + (n LM LN) / 2N
= 2(165) + 965 / 2 (2000)
= 0.3
q = f (L N) = ( 2n LN LN) + (n LM LN) / 2N
= 2 (965) + 870 / 2 (2000)
= 0.7
B) It is follwing Hardy-Weinberg equilibrium
