Blue eyes (b) are recessive to brown eyes (B). In a population of Swedes 64% of the individuals have blue eyes. In a population of Armenians, 9% of the individuals have blue eyes. Assuming that Hardy-Weinberg equilibrium holds for the Swedish and Armenian populations independently, what are the proportions of eye color genotypes in each population? Show your work.

Drosophila has four pairs of chromosomes: the sex chromosomes (XX in the females; XY in the males) and three pairs of autosomes. You are studying a new mutant strain with blue eyes. You wish to know if blue eye colour is a dominant mutation and on which chromosome the blue eye locus can be found. When you cross a pure-breeding female blue-eyed fly with vestigial wings and spineless bristles to a male fly with wild type eye colour, wings, and bristles, all of the F1 progeny are completely wild type. An F1 male is backcrossed to a triple mutant female, producing the following progeny (remember that there is no crossing over in Drosophila males):

Wild type eyes, wings, and bristles:	72 females, 69 males
Wild type eyes and bristles, vestigial:	83 females, 77 males
Wild type wings, blue eyes, spineless:	60 females, 65 males
Blue eyes, spineless, vestigial:	62 females, 58 males

a. Is the mutation dominant or recessive? Explain.

b. Since you know that the locus for vestigial wings is on chromosome 2 and the locus for spineless bristles is on chromosome 3, what chromosome carries the locus for blue eyes? Show your work, including the step-by-step reasoning you used to arrive at your answer.

c. When an F1 female is backcrossed to a triple mutant male, the following 1,000 progeny are produced:

Wild type eyes, wings, and bristles:	90 females, 89 males
Wild type eyes and bristles, vestigial:	83 females, 98 males
Wild type eyes and wings, spineless:	37 females, 35 males
Wild type wings and bristles, blue eyes:	36 females, 34 males
Wild type wings, blue eyes, spineless:	92 females, 88 males
Wild type eyes, spineless, vestigial:	34 females, 39 males
Wild type bristles, vestigial, blue eyes:	33 females, 37 males
Blue eyes, spineless, vestigial:	90 females, 85 males

Calculate the map distance between blue eye and any linked genes. Show your work.

You fished 100 drosophila out of your cup of tea this morning! There were 20 white, 70 red, and 10 orange eyed flies. This eye-color trait is controlled by a single locus, with 2 alleles. The red color allele is co-dominant, such that the individuals with orange colored eyes are heterozygotes.

a)What is the frequency of the red eye color allele?
b)What is the expected frequency of orange-eyed flies under Hardy-Weinberg equilibrium?
c)Is this population in Hardy-Weinberg equilibrium?
d) What is a plausible explanation of your result?
