In radishes, the gene that controls color exhibits incomplete dominance. Pure-breeding red radishes crossed with pure-breeding white radishes make purple radishes. What are the genotypic and phenotypic ratios when you cross a purple radish with a white radish?

Genotype Ratio = 1 RW: 1 WW

Phenotype = 1 Purple: 1 White

Explanation:

The gene for the color of radishes exhibits incomplete dominance and the heterozygous genotype gives purple color to radishes. The genotype of the heterozygous parent plant with purple radishes would be "RW." A cross between a purple radish (RW) and a white radish (WW) would give progeny in the following ratio.

well, that's easy; the answer's c, "it reduces contamination of the water and substrate of the estuary."
