F2 generation in a Mendelian cross showed that both genotypic and phenotypic ratios are same as 1: 2: 1. It represents a case of:
Co-dominance
Dihybrid cross
Monohybrid cross with complete dominance
Monohybrid cross with incomplete dominance
The conclusion from Punnett square -
All F1 are tall and in F2 3/4th of the plants are tall.
- wherein
Thus, phenotypic ratio of 3/4th tall: (1/4TT + 1/2Tt) and 1/4th tt, i.e 3:1 ratio but the genotypic ratio of 1:2:1
Monohybrid cross with incomplete dominance shows both genotypic and phenotypic ratio as same (1 : 2 : 1).
