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

  • codominance

  • dihybrid cross

  • monohybrid cross with complete dominance

  • monohybrid cross with incomplete dominance

Solution

D.

monohybrid cross with incomplete dominance

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)
