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 browneyed, RR gene combination and a parent with a heterozygous browneyed, 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 :)

Since the homozygous parent can only give R, the heterozygous parent determines the genotype, 50% RR and 50% RI.
In mathematics, a polynomial is an expression of finite length constructed from variables (also called indeterminates) and constants, using only the operations of addition, subtraction, multiplication, and nonnegative integer exponents. 
um, yeah, I'm sorry, but I have no idea what you are saying, please simplify and speak english.
