Asmall, flowering plant has white flowers with bright red spots on them. when this flowering plant is self-pollinated, it produces new plants with either red flowers, white flowers, or white flowers with red spots. what is the most likely explanation for this phenomenon? the red flower allele is recessive to the white allele. the red flower allele is incompletely dominant to the white allele. the red and white flower alleles are codominant. the red flower allele is dominant to the white allele.

The correct answer will be option-The red and white flower alleles are codominant.
Explanation:
The Mendel suggested that for any trait, the organism contains its alleles which could be dominant and recessive. But there are cases in which multiple alleles exist for the same trait which are neither dominant nor recessive.
Two cases arise due to this in which both the dominant alleles co-exist and show their phenotype effect called "co-dominance" and when both alleles form a new phenotype called 'incomplete dominance".
In the given case, the self-pollination produces red, white and patched flowers as a result of co-dominance because both the alleles show the equal effect on the flower petals (mixed phenotype) and form a flower with red patches or spots on the flower.
Thus, the selected option is the correct answer.
