please explain your reasons for the correct answer.
4. Drosophila have two genes y (yellow body) and car (carnationeyes). Doubly heterozygous females (y+ car+/y car) are mated tohemizyogous recessive males, and 50% percentage of the male progenyfrom such a female are be recombinant for y and car. Which of thefollowing statements is correct?
A. y and car are the same chromosome and 50 m.u. apart
B. y and car are the same chromosome and more than 50 m.u.apart.
C. y and car are on different chromosomes.
D. y and car are on different chromosomes or are on the samechromosome and more than 50 m.u. apart.
E. none of the above are correct.
5) If I tell you that genes A and B are on the same chromosome and70 map units apart, how did I determine this?
A) I did a cross and got 70% recombination between the twogenes
B) I did a cross and got 35% recombination between the twogenes
C) I did a cross and got 70% gene conversions
D) I did a cross and genes A and B showed both 35% recombinationwith gene C.
E) None of the above are correct.
