Webb2.4.3 Mendelian Patterns of Inheritance in Humans. In modern genetics, Mendelian principles have been extended to more complex inherited traits than Mendel described.

WebbThe basic principles of Gregor Mendel’s model of inheritance have held up for over a century. They can explain how many different characteristics are inherited, in a wide range of organisms including human beings. Some of the key elements of Mendel’s original model were: Heritable traits are determined by heritable factors, now called genes.
