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
$3 : 1 : :$ Tall : Dwarf
$3 : 1 : :$ Dwarf : Tall
$1 : 2 : 1 : : $ Tall homozygous : Tall heterozygous : Dwarf
$1 : 2 : 1 : :$ Tall heterozygous : Tall homozygous : Dwarf.
A cross between a homozygous recessive and a heterozygous plant is called
Heterozygous purple flower is crossed with recessive white flower. The progeny has the ratio
Which one of the following cannot be explained on the basis of Mendel’s law of dominance?
A cross between one tall plant and one dwarf plant resulted in offspring having tall plants. What would be the genotype of offsprings ?
In pea hybrids between red flowered and white flowered strains were crossed back to pure red flowered strain. The progeny of this cross will have
