Red flowers are (R) dominant. The allele for white flowers are color (r) is recessive.

Red Flower #1 is Rr and that the genotype of Red Flower #2 is RR.

What is the offspring for Box A and Box B?

• Box A and Box B are only red flowers

• Box A and Box B are only white flowers

• Box A has red and white flowers and Box B only has red flowers

• Box A has only red flowers and Box B has red flowers and white flowers
