In Mendel's monohybrid cross experiment,what was the percentage of heterozygous genotypes in the $F_2$ generation?

Based on which experiment was the Law of Purity of Gametes given by Mendel?

What is the genotypic ratio of Mendel's monohybrid cross?

If a dwarf pea plant was treated with Gibberellic acid,it grew as tall as a pure tall pea plant. If this treated plant is crossed with a pure tall plant,then the phenotypic ratio of the offspring is likely to be:

If two individuals with genotype $Bb$ are crossed and they produce two offspring,what is the probability that the second offspring will show the recessive trait,given that the first offspring shows the dominant trait?

In a plant,the genotype of the $F_1$ generation is $AABbCC$. Upon self-pollination of this plant,the phenotypic ratio in the $F_2$ generation will be:
