A pure pea plant having round (R), yellow (Y) seeds is crossed with another pure pea plant having wrinkled (r), green (y) seeds. Subsequently $\displaystyle \mathrm{F}_{1}$ progeny is self-pollinated to obtain $\displaystyle \mathrm{F}_{2}$ progeny.

What do the seeds of $\displaystyle \mathrm{F}_{1}$ generation look like ?

Give the possible combinations of traits in seeds of $\displaystyle \mathrm{F}_{2}$ generation. Also give their ratio.

State the reason of obtaining seeds of new combination of traits in $\displaystyle \mathrm{F}_{2}$ generation.
