QUESTION 5
1.   In Drosophila, the map positions of genes are given in map units numbering from one end of a chromosome to the other. The X chromosome of Drosophila is 66 m.u. long. The X-linked gene for body color-with two alleles, y + for gray body and y for yellow body-resides at one end of the chromosome at map position 0.0. A nearby locus  controlling bristle form, with f + for normal bristles and f for forked bristles is located at map position 1.5. A third X-linked gene for eye color, with alleles w + for red eye and w for white eye, is located at map position 56.7. Each gene resides on the X chromosome, and at each locus the wild-type allele is dominant over the mutant allele. Do you expect any of these gene pair(s) to assort independently?
 
   Yes, all the genes are expected to assort independently


 
   Yes, y and f are expected to assort independently of w


 
   Yes, y and w are expected to assort independently of f


 
   No, there are no genes expected to assort independently
