Question

Eye color is determined by genetic combination. Let R represent the gene for brown eyes and l represent the gene for blue eyes. Any gene combination including R represents browns eyes. Consider the offspring of a parents with homozygous brown-eyed, RR, gene combo and a parent with heteroz brown eyed, Rl, gene combo.

1. Show how you could use a polynomial to model the possible genetic combos of the offspring.

2. What percent of the possible genetic combos result in brown-eyed offspring?

3. What percent of the possible genetic combos are carriers for the blue-eyed gene?

4. Fill out a Punnett square to show your conclusions.
