In one gene inheritance pattern, if a yellow seeded pea plant is crossed with green seeded pea plant, the inferences that can be made from the $F_{2}$ generation individuals are
I. All plants are yellow seeded
II. Yellow and green seeded plants are obtained in 3:1 ratio.
III Yellow seeded homozygous and heterozygous plants are obtained in 1:2 ratio.
IV. Half of the plants are homozygous and half of them are heterozygous for the character.

Infinity Learn · Accepted Answer

In Mendelian pattern of single gene inheritance, in $$F2$$ generation the phenotypic ratio with respect to a single character is $$3$$:$$1$$ (3$$ yellow seeded and $$1$$ green $$seeded). The genotypic ratio in $$F2$$ is YY (homozygous$$ $$yellow) $$1$$: Yy (heterozygous$$ $$yellow) as $$2$$ : yy (homozygous$$ green or $$green) as $$1$$.
