Answer and Explanation:

The problem tells us that red is the dominant trait and white is the recessive. Since the problem says nothing about incomplete dominance or codominance, we can assume that this scenario illustrates that of a regular dominant-recessive allele situation.

When we cross a red flower (RR) with a white flower (rr), the possible genotype is: Rr. Since red (R) is dominant over white (r), this heterozygote Rr will have the dominant phenotype and appear red. There will be no pink because the alleles are not both dominant; instead, one is dominant and the other is recessive.

Hope this helps!
