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 results in brown eyes. Consider the offspring of a parent with a homozygous brown-eyed, RR gene combination and a parent with a heterozygous brown-eyed, Rl, gene combination.

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

There are several other questions that come with the passage, but I can probably do them once I figure out the polynomial part, which I am seriously stuck on. Thanks in advance for any help :)
