Toppr Admin · Accepted Answer

When none of the factors of a gene is dominant, the phenotype of a heterozygous dominant individual is a blend of dominant and recessive traits. This is called as incomplete dominance. For example, flower colour in Mirabilis jalapa or the 4 o'clock plants. The red flower is the dominant character and the white flower is recessive character. There is blending of the two alleles and the flowers in the F $_{1}$ generation will be pink in colour due to mixing of the alleles.
Thus, the correct answer is option C.
