Use the Hardy-Weinberg theorem for population in equilibrium to answer problems for the followings: suppose genes has two alleles, B and b, with B dominant. If the frequency of the alleles B is 0.7;

a) what percentage of the population display the phenotype B?

b) what percentage of the population are carriers for the recessive allele b?

c) what percentage of the population display the recessive phenotype?

d) if 16% of the people are left-handed and you randomly select a right-handed person (right-handedness is dominant) among all right-handers what is the chance (%) this individual is homozygous right-handed?

e)among all right-handers what is the chance (%) this individual is heterozygous right-handed?

If you know you are a carrier of a recessive trait that is expressed in only 1% of the population; what is the probability that your classmate is also carrier?

g)what percentage of the population are not carriers?

h) a breeder of exotic tulips finds two tulips out of 200,000 on a 2-acre field that show a unique flower shape;  how many of the remaining flowers are not true-breeding?
