Question

Pure tall pea plant with round seeds is crossed with pure dwarf pea plant with wrinkled seeds. The probability of genotype ttRR in F2 generation is (A) (1/16) (B) (3/16) (C) (9/16) (D) (6/16)

Mendelian dihybrid cross occurs between two pair of contrasting characters - height of plant and shape of seed. When these are crossed in the

F_{2}

generation we get the following genotypes and their count:

TTRR - 1, TTR r - 2, TT rr - 1,

TtRR - 2, TtR r - 4,

Tt rr - 2, ttRR - 1,

ttR r - 2 an d tt rr - 1

$\frac{1}{16}$

$\frac{3}{16}$

$\frac{9}{16}$

$\frac{6}{16}$
