genetic drift Flashcards
1
Q
Fst formula
A
Fst= (Hetero of Total - hetero of sub) / hetero of total
2
Q
effect of genetic drift on fittness peak
A
- Natural Selection CANNOT move from higher fitness to lower fitness
- Random shifts CAN move from peak to lower fitness value - genetic drift
3
Q
Effective population size, Ne
A
(4(Nbreeding males)(N females)) / (total)
4
Q
Impacts on smaller populations –> genetic drift
A
Alleles can become fixed or lost over
time
5
Q
gene flow effects
A
May reinforce or counteract selection and genetic drift
6
Q
gene flow is
A
the movement of alleles into and out of populations
