Monohybrid cross predicts that three quarters of the F2 generation will have the dominant allele's phenotype. And the remaining quarter of the F2s will have the recessive allele's phenotype. This predicted 3:1 phenotypic ratio assumes Mendelian inheritance. This cross was originally used by biologist Gregor Mendel, who crossed two pea plants to obtain a hybrid variety and discovered the dominance relationships between alleles of several genes. Mendel has considered one alleleomorph character for his first experiment that is colour of red and white length of plant-tall and dwarf. Gregor Mendel (1822–1884) was an Austrian monk who theorized basic rules of inheritance. From
Gregor Mendel next thirty-five years. His paper was criticized at the time, but is now considered a seminal work. Notably, Charles Darwin was not aware of Mendel's paper, and it is envisaged that if he had been aware of it, genetics as we know it now might have taken hold much earlier. Mendel's scientific biography thus provides an example of the failure of obscure, highly original, innovators to receive the attention they deserve. Mendel began his studies on heredity using mice. He was at St. Thomas's Abbey but his bishop did not like one of his friars studying animal sex, so Mendel
