Question

Apply the general viability selection model to answer the following hypothetical problem. In the plant Clarkia tembloriensis, temporal variation in germination date is under the control of a single locus. In dry habitats where pollinators are not abundant, the early germinating, recessive genotype (ll) is favored over the late germinating genotypes (LL and Ll). Assume the following data come from a population in a dry habitat and that zygotes are formed by random mating prior to selection.
Genotype: LL Ll ll
Number before selection 36 48 16
Number after selection 24 32 14

The fitnesses at the L locus are indicative of what form of selection?

Population mean fitness at the L- locus?

What are the genotype frequencies at the L-locus after selection?

After selection, the frequencies of the L and l alleles are equal to (pL, q)?

Any help would be greatly appreciated!

Explanation / Answer

Genotypic frequencies Before and After selection-

This is calculated by first finding total population before selection i.e. 100, then for LL= 36/100= 0.36 and so on.

This can be BALANCING SELECTION as hetero state has higher frequency.

The allelic frequencies after selection of L and l are p= 0.58 (L) & q= 0.44 (l), so not equal.
