| (1) | Law of Unitary Trait. Any hereditary trait is controlled by a hereditary unit. Hereditary units will not interfere each other. |
| (2) | Law of dorminance and recessiveness Each hereditary unit is composed of 2 factors. The presentations of these 2 factors can be different. If an individual in a certain hereditary trait possesses 2 different factors, only one of them can show its character. But the next cannot. The factor that can present its character is said to be dominance. Otherwise, it is said to be recessive. This is called the Law of Dominance and Recessiveness. |
| (3) | Mendel's first Law of inheritance --- Law of Segregation The Law of Segregation states that in the process of producing offsprings, the factors of a gene would be separated. During the course of separation, they will not be affected by factors of another gene. |
| (4) | Mendel's second Law of inheritance --- the Law of Independent Assortment In the process of forming new offsprings, factors controlling a certain hereditary trait would be paired after separation. The pairing of the factors of a specific trait will not be affected by the factors of another trait. |
