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
Muriel Wheldale Onslow teachings. In 1900 she entered Newham College, Cambridge and took a class in Natural Sciences Tripos. In 1903 she joined William Bateson's genetics lab at Cambridge where she began her study focusing on the interaction of factors and of the inheritance of petal color in Antirrhinum (snapdragons). William Bateson was the English biologist who was the first person to use the term genetics to describe the study of heredity, and the chief populariser of the ideas of Gregor Mendel following their rediscovery in 1900. Bateson and Onslow carried out a series of breeding experiments in various plant and animal species
