Read the following statement. On the basis of your reading, answer the given question:
Vyom saw Snapdragon plant in a nursery and got curious about the colours of its flowers. He discussed it with his botany professor and learnt about incomplete dominance.
Incomplete dominance is when a dominant allele, or form of a gene, does not completely mask or eliminate the effects of a recessive allele, and the organism's resulting phenotype shows a blending of both alleles. In case of dog flower, the cross breeding of red and flowered plants lead to the production of all intermediate pink coloured flowers in F generation.

If we consider incomplete dominance, the intermediate colour appears in:

Options

A. homozygous dominant plant
B. heterozygous dominant plant
C. pureline dominant plant
D. homozygous recessive plant

Answer

A

Explanation

Incomplete dominance is when a dominant allele, or form of a gene, does not completely mask the effects of a recessive allele, and the organism.s phenotype includes a blending of both alleles.
Hence, the heterozygous dominant plant would have intermediate colour.
