When a true breeding  violet flowered pea plant is crossed with white flowered pea plant all the members of the ${\mathrm{F}}_1$ generation will have violet flowered pea plants. When self- fertilization is done in these plants what will be the genotypic ratio of the violet flowered pea plant in the ${\mathrm{F}}_2$generation?

• A

  1: 1 as heterozygous to homozygous violet flowered plants

• B

  3:1 as heterozygous to homozygous violet flowered plants.

• C

  1: 4 as homozygous to heterozygous violet flowered plants

• D

  1:2 as homozygous to heterozygous violet flowered plants
