Question

Incomplete Dominance Monohybrid Cross

Answer 1

a) RR red  BB Blue and RB purple are the genotypes of flower colour in incomplete dominance.

b) 0% probability

c) There is 100% probability of purple colour flowers

d) 0% probability

Explanation:

a)If a poofkin with red flower is crossed with blue flowers:

Alleles for red colour RR

Alleles for blue colour BB

By Punnett square:

    R     R

B   RB  RB

B    RB  RB

b) genotype of red flower =  no red flower hence 0% probability

c) probability of purple flowers =  100%

d) probability of blue flowers = 0% probability

The incomplete dominance is a phenomenon in which both the genotypes are expressed in the phenotype of the progeny. It occurs when both the alleles of the gene are dominant over each other resulting into intermediate characteristic. The heterozygous progeny will be the intermediate in phenotypic characters.
