Question

In radishes, red (R) and white (W) are pure-breeding colors, while hybrids are purple (RW). If a red radish is crossed with a white radish, what will be the phenotype of the offspring? Show the Punnett Square and percentage of each phenotype.
Help please

Answer 1

Explanation:

We have a case of incomplete dominance (purple is an intermediate heterozygous phenotype in radishes)

Parental genotype => RR x WW

F1 genotypic ratio => RR:RW:WW = 1:2:1

F1 phenotypic ratio

=> Red : Purple : White = 1:2:1.
