  • In the F2 generation of a Mendelian dihybrid cross the number of phenotypes and genotypes are: a. phenotypes – 4; genotypes – 16 b. phenotypes – 9; genotypes – 4 c. phenotypes – 4; genotypes – 8 d. phenotypes – 4; genotypes – 9

In the F2 generation of a Mendelian dihybrid cross the number of phenotypes and genotypes are:

a. phenotypes – 4; genotypes – 16

b. phenotypes – 9; genotypes – 4

c. phenotypes – 4; genotypes – 8

d. phenotypes – 4; genotypes – 9

Answers (1)

The answer is the option (d) Phenotypes – 4; genotypes - 9

Explanation: For example, consider a dihybrid cross between wrinkled green (rryy) and round yellow (RRYY). The phenotypes were as follows: round green, round yellow, wrinkled green and wrinkled yellow and the genotypes were: rryy, rrYy, rrYY, Rryy, RrYy, RrYY, RRyy, RRYy, and RRYY. Hence, correct option is (d).
