I need help fast! Will give brainliest away to correct answer!

Eye color is determined by genetic combination. Let R represent the gene for brown eyes and
I 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, RI, gene combination.
Show how you could use a polynomial to model the possible genetic combinations
of the offspring.

Answer:

  (R +R)(R +I) = RR +RI +RR +RI

Step-by-step explanation:

Polynomial multiplication will give all pairings of a gene from one parent with a gene from the other parent:

     (R +R)(R +I) = RR +RI +RR +RI

Each binomial represents the genes one parent may contribute to the mix. Each product term represents one possible offspring's set of genes.

__

Assuming each possibility is equally likely, the probability is 2/4 = 50% that the offspring will be heterozygous.
