Question

Use the Hardy-Weinberg theorem for population in equilibrium to answer questions 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?;i) suppose you and 68% of the population display a dominant trait;what is the frequency of the dominant allele?
