WebApr 9, 2024 · After that Mendel self-fertilized the first generation and obtained a 3:1 ratio, this is how he proved that genes can be paired in 3 possible ways: AA, aa, Aa. A represents the dominant factor, and a represents the recessive factor. Results Combining all the Laws of Mendel and the theories proposed, the science of heredity becomes clearer. WebThe expected genotypic ratio refers to the one that was calculated by Mendel during his experiments on inheritance. The most common method of calculating the genotypic ratio is by making a Punnet square with zygotes derived from the F1 generation. In more complex cases as the number of alleles involved increases other methods such as the fork ...
