task
Skaldness in man is a gender-influenced character, determined by two alleles in an autosomal locus. Allel B for skaldness is dominant in men, but recessive in women. The alternative allele b is recessive in men, but dominant in women.
In a large population (A) it turned out that 1% of the women were bald (skaldede). Answer the following questions assuming that the population is in Hardy-Weinberg's balance with regard to the genetic system considered.
a) Calculate the expected frequency of heterozygous women among women in population A.
b) Calculate the expected frequency of bald men in population A.
c) How much of all marriages are the marriage combination (bald woman) x (non-bald man)?
d) What is the probability that the first son from a marriage between a non-bald man and a randomly taken non-bald woman will be bald?
In another large population (B) - also in the Hardy-Weinberg equilibrium - 50% of the men were bald.
e) Calculate the expected frequency of bald women in population B.
f) How much of all marriages can be expected (bald man) x (non-bald woman) in population B?
I want to say that I hav'nt got answer for question c) and f) . And ansewer e) is not complete. and try to give me please more details and explaining.
