Detailed explanation-1: -This pattern of inheritance is described as incomplete dominance, meaning that neither of the alleles is completely dominant over the other: both alleles can be seen at the same time. The allele for red flowers is incompletely dominant over the allele for white flowers. Red + white = pink.
Detailed explanation-2: -The crossing of a red flowered plant and a white flowered plant produces all the offspring with pink flowers. This cross illustrates red and white exhibit incomplete dominance. This situation occurs due to the blending of both the alleles.
Detailed explanation-3: -So, the correct answer is ‘Heterozygous’.
Detailed explanation-4: -A phenotype is a description of what an organism looks like based on its genotype. A person with the Rr genotype for tongue rolling would be able to roll his or her tongue, because he or she has the dominant allele that allows tongue rolling.
