In Missouri in 2004, a total of 127 HIV-related deaths occurred in males and 17 HIV-related deaths occurred in females. The estimated 2004 midyear population in Missouri was 2,810,852 males and 2,943,766 females.

Calculate the HIV-related death rate for males and for females.

What type of mortality rates did you calculate in step a?

Calculate the HIV-mortality rate ratio for males versus females.

Drosophila has four pairs of chromosomes: the sexchromosomes (XX in the females; XY in the males) and three pairs ofautosomes. You are studying a new mutant strain with blue eyes. Youwish to know if blue eye colour is a dominant mutation and on whichchromosome the blue eye locus can be found. When you crossa pureâbreeding female blueâeyed fly with vestigial wings andspineless bristles to a male fly with wild type eye colour, wings,and bristles, all of the F1 progeny are completely wild type. An F1male is backcrossed to a triple mutant female, producing thefollowing progeny (remember that there is no crossing over inDrosophila males):

Wild type eyes, wings, andbristles: 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, 58males

Is the mutation dominant or recessive?Explain.

Since you know that the locus for vestigial wings is onchromosome 2 and the locus for spineless bristles is on chromosome3, what chromosome carries the locus for blue eyes? Showyour work, including the stepâbyâstep reasoning you used to arriveat your answer.
