Question
  1. In Drosophila, the following genes and mutations are known:
  1. Wingsize – recessive allele for tiny wings – t; dominant allele for normal wings – T
  2. Eye shape – recessive allele for narrow eyes – n; dominant allele for normal (oval) eyes – D
  3. Eye color – recessive allele for white eyes – r; dominant allele for normal (red) eyes – R

The following cross is performed and the offspring analyzed – TtDdRr X Ttddrr.  Give the probabilities for generating the following offspring. Show your work below.
