A pea plant with pure yellow (YY) and round (RR) seeds were crossed with a plant having pure green (yy) wrinkled (rr) seeds.
On which law, following is based:
The off-springs of the F-₁ generation are self-pollinated.

Solution

Law of dominance:
In the experiment, a cross is made between a homozygous plant with yellow round seeds(YYRR) and a homozygous plant with green wrinkled seeds (yyrr).
In the F-₁ generation, all the off-springs show yellow round seeds(YyRr).
It can be seen in Punnett square.

The yellow and round characters expressed are dominant while wrinkled and green characters that are not expressed are recessive.
Mendel postulated, this explanation as to the Law of dominance.

Mendel first crossed pure-bred pea plants having round -yellow seeds with pure-bred pea plants having wrinkled -green seeds and found that only round- yellow seeds were produced in the $F_{1}$ generation. When $F_{1}$ generation pea plants having round-yellow seeds were cross-bred by self-pollination, then peas having round-yellow seeds, round green seeds, wrinkled-yellow seeds and wrinkled -green seeds were produced. Mendel collected a total of 2160 seeds.
