Frage 1
Frage
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’).

more than 2
-
2 or more

Frage 6
Frage
True or False:
Inbreeding results in the frequency of heterozygotes halving each generation.
Antworten
- True
- False
Frage 7
Frage
True or False:
Self-fertilisation results in the frequency of heterozygotes halving each generation.
Antworten
- True
- False
Frage 8
Frage
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)
