Question

During dihybrid cross, in the $F_2$ generation, the ratio of individuals showing one dominant and the other recessive character will be ........... of parents with contrasting characters.

• A. $\frac{4}{16}$
• B. $\frac{6}{16}$
• C. $\frac{8}{16}$
• D. $\frac{9}{16}$

Answer 1

Answer: (B)

$\frac{6}{16}$

• The $F_2$ phenotypic ratio of a dihybrid cross is 9 (both dominant traits): 3 (one dominant and other recessive): 3 (one dominant and other recessive): 1 (both recessive traits).
• The ratio of individuals showing one dominant and the other recessive character will be 6/16.
  So, the correct answer is option B.
