Mendel proposed the Law of Purity of Gametes based on:

$A$ cross was made between a pure tall and a pure dwarf pea plant to produce progeny. The progeny was self-pollinated. Find the ratio of the resulting true-breeding tall and dwarf plants.

If a heterozygous red-flowered plant is crossed with its pure-breeding red-flowered parent,the offspring will show:

$A$ true-breeding plant producing red flowers is crossed with a pure plant producing white flowers. The allele for the red color of the flower is dominant. After selfing the plants of the first filial $(F_1)$ generation,what would be the proportion of plants producing white flowers in the progeny?

What will be the nature of a hybrid plant produced from two alternative alleles?

In a monohybrid cross,if you get a $3:1$ ratio,it denotes that:
