#10.A population is at genetic equilibrium if
Select one:
a. there is no change in population numbers over time
b. small populations migrate slowly
c. there is no change in allele frequencies over time
d. superior breeding mates are selected
#11.The M and N factors are glycoproteins that are found on the surface of red blood cells. Unlike other types of red blood cell antigens, The M and N factors do not cause antibody reactions in human blood transfusions. People with type M blood are homozygous for the M allele, and people with type N blood are homozygous for the N allele. Heterozygous individuals have type MN blood. In a study of population of Inuit living in the Northwest Territories, 512 people have blood type M, 256 had blood type MN, AND 32 has blood type N. a).Calculate the frequency of each allele, M and N, in the population studied.
b) What would be the expected frequency of each genotype in the next generation, assuming that this population is in genetic equilibrium for the trait.
c) In a second study group, the frequencies of the genotypes were 0.306 MM, 0.491 MN, and 0.203 NN. Could this second study group have, in fact, come from the previously described Inuit population? Explain your answer.
for #10 i'm stuck between a and b because both are correct
#11 a). work p=512/800=0.80
1-0.80=0.20=q.
b) 2(p)(q)=2(0.80)(0.20)=0.32
they said in the question what's the total # in the population
so i took 0.32x800 and got 256
for c) I used this formula: p^2+2pq+q^2=1
0.306+0.491+0.203=1
Yes i believe that the second study group came from the information given in the question becasue most of my answers are from the information given above. example: 256 was given in to me in the question as MN blood type...
is this correct? for #11 and i still can't figure out #10
