Modern genetics began in the 1860's when Gregor Mendel, an Augustinian monk, discovered the fundamental principles of heredity. He came up with multiple theories such as the Particulate Theory of heredity which states that parents transmit genes to their children that remain as separate factors from one generation to the next. While attending the University of Vienna, Professor Doppler, a physicist, trained him to apply a quantitative experimental approach to the study of natural phenomena.

…showed last 75 words of 623 total…is a pattern of inheritance in which the dominant phenotype is not fully expressed in the heterozygote. This is called incomplete dominance, where the resulting phenotype is an intermediate between the homozygous dominant and homozygous recessive. For example, when a red (RR) four o'clock flower is crossed with a white (rr) four o'clock flower, the resulting heterozygotes (Rr) have pink flowers because the heterozygotes produce one-half as much red pigment as the homozygous red-flowered plant.
