In Britain the stiff upper lip (SUL) allele is much more common than the emotional outburst (EO) allele. But if the Great British Bake Off is anything to go by, the EO allele is increasing rapidly. Perhaps there is a heterozygote advantage to being able to show a range of emotional responses?
Survival rates are:
SUL/SUL genotype = 0.8
SUL/EO genotype = 1.0
EO/EO = 0.7
a. What is the selection coefficient s?
b. what is the selection coefficient t?
c. How many Brits will still show the stiff upper lip phenotype at equilibrium?
