Question

for the following problem please provide me a key for allele symbols, the genotype for each parent, a punnett square with the male and female symbols, and answers to the questions.
codominance is also seen in plants. a "female" rhododendron with only red flowers is crossed with a "male rhododendron with only white flowers. what will the genotypes and phenotypes of the offspring be?

Answer 1

Key for allele symbols
- R = red allele (codominant)
- W = white allele (codominant)

Genotype of each parent
- Female (red flowers only): ♀ = RR
- Male (white flowers only): ♂ = WW

Punnett square (female across the top, male down the side)
♀: R R
♂ W RW RW
♂ W RW RW

Answers
- Genotypes of offspring: 100% RW (all heterozygous).
- Phenotypes of offspring: 100% show codominant expression — each offspring will display both red and white in their flowers (e.g., red-and-white mottled or striped flowers).

(Brief note: this is codominance, not incomplete dominance — heterozygotes express both parental colors rather than an intermediate color like pink.)
