In one of Mendalian experiments, when $\displaystyle \mathrm{F}_{1}$ generation pea plants with round yellow seeds were self-pollinated, pea seeds with the following combinations were obtained in $\displaystyle \mathrm{F}_{2}$ generation :

Seeds	Round yellow	Round green	Wrinkled yellow	Wrinkled green
