Study Questions - Modeling Selection
1) Consider this population. Calculate the genotypic frequencies after one generation of selection.
What type of selection is this? How will delta-p change over the course of several generations? Why?
p=0.3 q = 0.7 | AA | Aa | aa | |
parental zygotes | 0.09 | 0.42 | 0.49 | = 1.00 |
prob of survival | 0.8 | 0.8 | 0.4 | |
rel. fitness | ||||
genotypic frequencies in the reproductive adults | ||||
gene frequencies in the gene pool | ||||
Genotypic frequencies in the F1 |
2) Consider this population (yes, it's different):
p=0.3 q = 0.7 | AA | Aa | aa | |
parental zygotes | 0.09 | 0.42 | 0.49 | = 1.00 |
prob of survival | 0.6 | 0.8 | 0.4 | |
rel. fitness | ||||
genotypic frequencies in the reproductive adults | ||||
gene frequencies in the gene pool | ||||
Genotypic frequencies in the F1 |
What will happen over time? Where will p equilibrate?
