Question

Ratio of parental and recombinant phenotypes in a dihybrid cross would be

• A. 8 : 8
• B. 6 : 10
• C. 10 : 6
• D. 9 : 7

Answer 1

The correct option is C 10 : 6

In the Mendel dihybrid cross, in the F₂ generation, 16 progeny are formed. In these progeny, 10 progeny show parental phenotypes(9 Yellow round + 1 green, wrinkled) and 6 progeny show recombinant phenotypes(3 Yellow wrinkled + 3 green round). The ratio is 10:6 (flow chart 17)

So, the correct option is ’10:6’.
