A population is polymorphic for a particular trait when the population has more than 2 2 or more( more than 2, 2 or more ) phenotypes for that trait (each being >1%, so not ‘rare’).
True or false: The frequency of an allele is determined [at least in part] by its dominance?
Based on the image above, what are the [at least expected] allele frequencies:
B = 0.2
B = 0.8
b = 0.2
b = 0.8
B = 0.04
b = 0.04
B = 0.64
b = 0.64
Based on the image above, what are the [at least expected] gene frequencies:
BB = 0.04
Bb = 0.16
bB = 0.16
bb = 0.64
Black = 0.36
Black = 0.64
Yellow = 0.64
Yellow = 0.36
Based on the image above, what are the [at least expected] phenotype frequencies:
B_ = 0.36
bb = 0.36
B_ = 0.64
True or False: Inbreeding results in the frequency of heterozygotes halving each generation.
True or False: Self-fertilisation results in the frequency of heterozygotes halving each generation.
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)
