Hi, I would really appreciate someone helping me out with this problem or at least showing me how to go about calculating it. Thank you!
----------------------------------------------------------------------------------
Q) Suppose there is a gene with two alleles D and d in Hardy-Weinberg Equilibrium. Further suppose the d allele has a frequency of 0.4 and causes trait Y in a recessive fashion.
a) What is the prevalence of individuals without trait Y?
b) What is the probability that two individuals with trait Y will mate (given the assumptions of Hardy-Weinberg equilibrium hold)?
c) What is the probability that an offspring of the above mating will not have trait Y?
d) Suppose two individuals – who do not have trait Y themselves but both have offspring from previous marriages that do have the trait – mate and have 2 children. What is the probability that both children have trait Y?
