What genotype produces white flowers in the described plant species?

To determine which genotype produces white flowers in the given plant species, it's essential to consider the genetic basis of flower color inheritance typically involving multiple alleles. In plant genetics, particularly if we consider flower color as a trait influenced by alleles, certain combinations can lead to specific phenotypes.

The correct answer indicates that the genotype CWCW DWDW produces white flowers. Here, it is assumed that the C and D alleles correspond to color genes where CW might represent a color that results in white flowers when homozygous. Generally, if a plant exhibits a homozygous condition (like CWCW), it may express the traits associated with that specific combination uniformly. In many plant species, dominant and recessive alleles determine the flower color, and in this case, the homozygous recessive combinations lead to a phenotype of white flowers.

Other genotypes provided include variations in both C and D alleles, which could result in different colors based on their dominance hierarchy (For instance, CR may denote a red color allele). Consequently, combinations like CRCR DRDR or CRCW DRDW would likely express color traits that are not associated with the white phenotype, given that they involve homozygous or heterozygous dominant alleles
