Answer to Question #42576 in Other Biology for henry
Assume that you are working with Drosophila and are studying genes, a, b, c, d, e, and f that are all linked in a region on a chromosome, but their order is unknown. In your work, you find that five deletions in the same region uncover recessive alleles of the genes as follows: Deletion 1 uncovers a, b, and c. Deletion 2 uncovers a and c. Deletion 3 uncovers a, c, and e. Deletion 4 uncovers c, d, and e. Deletion 5 uncovers d, e, and f. a. What is the order of the genes? b. Suppose you systematically attempt to generate a chromosomal deletion (using X‐rays) that lacks all five genes, but you are unsuccessful. Suggest a plausible explanation for this.
