Homozygous advantage

Detailed explanation-1: -The intermediate trait appearance in between the phenotypes of homozygous traits in the heterozygote is called incomplete dominance.
Detailed explanation-2: -Indeed, “codominance” is the specific term for a system in which an allele from each homozygote parent combines in the offspring, and the offspring simultaneously demonstrates both phenotypes. An example of codominance occurs in the human ABO blood group system.
Detailed explanation-3: -Figure 21: A cross between a red and white snapdragon will yield 100% pink offspring. 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.
Detailed explanation-4: -When a red snapdragon is crossed with a white one all their offspring are pink .
Detailed explanation-5: -So, the correct option is ‘25%’.
