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
Adoption detective their parents is information that has been used since prehistoric times to improve crop plants and animals through selective breeding. The biological science of genetics, which began with the work of Gregor Mendel in the mid-nineteenth century, seeks to understand the process of inheritance and the physical basis for heredity in our DNA. What is known about human traits inherited through patients' families can save their lives—that is why gathering a person's complete and accurate medical family history is extremely important even as genetic medicine continues to explain more diseases. Many advances in biological medical science are anticipated in the
