The answer is B) roan x roan.
Let's summarize:
R - dominant allele,
r - recessive allele,
<u>RR </u>- dominant homozygous with <u>red color</u>,
<u>rr </u>- recessive homozygous with <u>white color</u>,
<u>Rr </u>- heterozygous with <u>roan color</u>.
If we cross two heterozygous (Rr):
Parents: Rr x Rr
Offspring: RR Rr Rr rr
then, the offspring will be: <u>1 red</u> (RR) : <u>2 roan</u> (Rr, Rr ) : <u>1 white</u> (rr).
