Question

How does dominance differ from incomplete dominance?

Answer 1

Dominance - Dominant gene masks recessive gene completely and deprives it from gene expression.

Incomplete dominance - Dominant gene masks recessive gene partially resulting in intermediate phenotypes.

Eg:

Dominance: Heterozygous individuals of pea plant are tall. Tall gene masks expression of dwarf recessive gene completely.

Incomplete dominance: Heterozygous individuals in cross between red and white Snapdragon flower is pink. Red gene masked white gene incompletely resulting in an intermediate color.

Answer 2

➡️DOMINANCE:in this condition,the dominant allele is fully expressed(ex:if a tall plant and a short plant is crossed then the new plant will be tall as tallness is the dominant characteristic)

INCOMPLETE DOMINANCE:in this condition, no allele is fully expressed (ex:if a plant with red flowers is crossed with a plant with white flowers,the new plant will have pink flowers (mixture of red and white).
