Question

a red flowered plant (rr) breeds with a white flowered plant (ww). the gene for petal color in these plants expresses incomplete dominance. what percentage of the offspring will have pink (rw) flowers? 25% 0% 50% 100%

Explanation:

Step1: Determine Parental Genotypes

The red - flowered plant has a genotype of \(RR\), so it can only produce gametes with the \(R\) allele. The white - flowered plant has a genotype of \(WW\), so it can only produce gametes with the \(W\) allele.

Step2: Analyze Offspring Genotypes

When we cross \(RR\) (red - flowered) with \(WW\) (white - flowered) in a case of incomplete dominance, all of the offspring will have the genotype \(RW\). Because incomplete dominance means that the heterozygous genotype (\(RW\)) results in an intermediate phenotype (pink in this case). Since all offspring have the \(RW\) genotype, the percentage of offspring with pink (\(RW\)) flowers is \(100\%\).

Answer:

\(100\%\)
