medium
A tall true breeding garden pea plant is crossed with a dwarf true breeding garden pea plant. When the $F_1$ plants were selfed the resultinggenotypes were in the ratio of
A
$3 : 1 : :$ Tall : Dwarf
B
$3 : 1 : :$ Dwarf : Tall
C
$1 : 2 : 1 : : $ Tall homozygous : Tall heterozygous : Dwarf
D
$1 : 2 : 1 : :$ Tall heterozygous : Tall homozygous : Dwarf.

Solution
(c) : When a tall true breeding garden pea plant is crossed with a dwarf true breeding garden pea plantand the $F_1$ plants were selfed the resulting genotypes were in the ratio of $1 : 2 : 1$
$i.e.$, Tall homozygous :Tall heterozygous : Dwarf
