1. You cross two true-breeding flies in the P generation. The female parent is brown and wingless and the male parent is black with normal wings. All of the flies in the \( \mathrm{F} 1 \) generation are brown and have normal wings. Assume the genes are not found on a sex chromosome. When you count the F2 generation, you actually get 85 brown, winged flies, 728 black, winged flies, 712 brown, wingless flies, and 75 black, wingless flies. These results indicate that the body color and wing size are linked genes. a. What are the phenotypes of the recombinant flies? (Hint: Refer back to the P generation flies in the first paragraph. Recombinant flies do not resemble the original P generation phenotypes.) b. Calculate the recombination frequency (\%) between the linked genes for body color and wing size.
