In deer, the gene $N$ is for normal coloring and the gene $a$ is for no coloring, or albino. Any gene combination with an $N$ results in normal coloring. The Punnett square shows the possible gene combinations of an offspring and the resulting colors from parents that both have the gene combination $Na$ . a. What percent of the possible gene combinations result in albino coloring?

$\%$

b. Show how you could use a polynomial to model the possible gene combinations of the offspring.

The gene combinations could be modeled by the polynomial
