Questão 1
Questão
A population is polymorphic for a particular trait when the population has [blank_start]________[blank_end] phenotypes for that trait (each being >1%, so not ‘rare’).
Responda
-
more than 2
-
2 or more
Questão 2
Questão
True or false:
The frequency of an allele is determined [at least in part] by its dominance?
Responda
- True
- False
Questão 3
Questão
Based on the image above, what are the [at least expected] allele frequencies:
Responda
-
B = 0.2
-
B = 0.8
-
b = 0.2
-
b = 0.8
-
B = 0.04
-
b = 0.04
-
B = 0.64
-
b = 0.64
Questão 4
Questão
Based on the image above, what are the [at least expected] gene frequencies:
Responda
-
BB = 0.04
-
Bb = 0.16
-
bB = 0.16
-
bb = 0.64
-
Black = 0.36
-
Black = 0.64
-
Yellow = 0.64
-
Yellow = 0.36
-
B = 0.2
-
b = 0.8
Questão 5
Questão
Based on the image above, what are the [at least expected] phenotype frequencies:
Responda
-
B_ = 0.36
-
bb = 0.64
-
Black = 0.36
-
Black = 0.64
-
Yellow = 0.64
-
Yellow = 0.36
-
bb = 0.36
-
B_ = 0.64
Questão 6
Questão
True or False:
Inbreeding results in the frequency of heterozygotes halving each generation.
Responda
- True
- False
Questão 7
Questão
True or False:
Self-fertilisation results in the frequency of heterozygotes halving each generation.
Responda
- True
- False
Questão 8
Questão
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)
