The hereditary units located on the chromosomal thread are called genes. When there is a change in the composition of the gene due to external or internal factor, it is termed as a mutation. It plays a crucial role in evolution. To explain a mutation in the gene can cause disease, Mendel came up with three laws and were called Mendel’s law of inheritance:
- Law of Dominance
- Law of segregation
- Law of independent assortment
