The pattern of inheritance of simple traits depends on whether the traits are … 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. WebbHe described three laws of inheritance: Law of Dominance To explain the law of dominance, Mendel had given three postulates: Discrete factors or units direct phenotypic traits. The factors always comprise a couple of pairs are called “ Alleles ”. In two dissimilar alleles, one will show dominant characters, and the other will show recessive traits. tss agents
