Mendel proposed the Law of Purity of Gametes based on:

$A$ cross between one tall plant and one dwarf plant resulted in offspring having tall plants. What would be the genotype of offsprings?

When a pure tall plant is crossed with a pure dwarf plant,and the resulting hybrid plants are self-pollinated,what will be the phenotypic ratio of the offspring in the $F_2$ generation?

$A$ cross between $AaBB$ and $aaBB$ produces which type of genotype?

Which of the following is the genotypic ratio of Mendel's monohybrid cross?

$A$ 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?
