Question

F₂-generation in a Mendelian cross showed that both genotypic and phenotypic ratios are same as 1 : 2 : 1. It represents a case of

(a) codominance 

(b) dihybrid cross

(c) monohybrid cross with complete dominance 

(d) monohybrid cross with incomplete dominance

Answer 1

Correct option (d) monohybrid cross with incomplete dominance

Explanation

Monohybrid cross with incomplete dominance shows both genotypic and phenotypic ratio as same (1 : 2 : 1).

Genotypic ratio - 1 (AA) : 2 (Aa) :1 (aa) 

Phenotypic ratio - 1 (Red) : 2 (Pink) : 1(white)
