Questions: Red (R) is dominant and masks the recessive white allele (r). Which of the following genotypes would have white flower phenotype? a. RR b. π c. Rr

The answer is none of the given options.

Explanation for each option: a. RR: This genotype consists of two dominant alleles (R), which would result in a red flower phenotype, not white. b. $\pi$: This is not a valid genotype notation in the context of genetics. It does not correspond to any alleles related to flower color. c. Rr: This genotype consists of one dominant allele (R) and one recessive allele (r). The presence of the dominant allele (R) would mask the recessive allele (r), resulting in a red flower phenotype, not white.

Summary: None of the provided genotypes (RR, $\pi$, Rr) would result in a white flower phenotype. For a white flower phenotype, the genotype would need to be rr, where both alleles are recessive.
