Question 1 of 8

1

Select from the dropdown list to complete the text.

A population is polymorphic for a particular trait when the population has ( more than 2, 2 or more ) phenotypes for that trait (each being >1%, so not ‘rare’).

Explanation

Question 5 of 8

2

Based on the image above, what are the [at least expected] phenotype frequencies:

Select one or more of the following:

B_ = 0.36
bb = 0.64
Black = 0.36
Black = 0.64

Explanation

Question 6 of 8

1

True or False:
Inbreeding results in the frequency of heterozygotes halving each generation.

Select one of the following:

True
False

Explanation

Question 7 of 8

1

True or False:
Self-fertilisation results in the frequency of heterozygotes halving each generation.

Select one of the following:

True
False

Explanation

Question 8 of 8

1

The inbreeding coefficient (F) adjusts genotype frequencies of ( A1A1 : A1A2 : A2A2 ) from ( p^2 : 2pq : q^2 ) to ( p^2 + Fpq : 2pq – 2Fpq : q^2 + Fpq ). Thus if a population expected to be ( 9 : 42 : 49 ) is observed at ( 20 : 20 : 60 ), what is F?
(...assume the only reason for the departure from expecteds is inbreeding)
