In snapdragon plants, neither one of the petal colors is dominant to the other. The hybrids have a intermediate phenotype. If a homozygous red flower is crossed with a homozygous white flower, What will the offspring’s phenotype be?_____________________________
(Use C for color, and a superscript R or W to denote red and white)
Genotype of red flower ______________
To determine the offspring's phenotype, we need to consider the genotypes of the parent flowers and the inheritance pattern of the petal color in snapdragon plants.
Let's denote the genotype of the red flower as RR and the genotype of the white flower as WW.
In snapdragon plants, when neither color is dominant over the other, and the hybrids exhibit an intermediate phenotype, the inheritance pattern is known as incomplete dominance. In this pattern, a blending of traits occurs, resulting in an intermediate trait in the offspring.
In the case of snapdragon plants, the blending of red and white petals results in pink petals.
Therefore, when a homozygous red flower (RR) is crossed with a homozygous white flower (WW), the offspring's phenotype will be pink (RW).
So, the answer to the question is: The offspring's phenotype will be pink (RW).
Please note that we're assuming there are no other genetic factors influencing the petal color trait in this scenario.
