→There are three laws of Mendel's inheritance :-
1) Law of paired factor :-
→According to Mendel each genetic character is controlled by a pair of unit factor.
→It is known as conclusion of paired factor or unit factor.
2) Law of dominance :-
→This conclusion or law is based on F1 generation.
→When two different unit factors are present in single individual,only one unit factor is able to express itself and known as dominant unit factor.
→Another unit factor fails to express itself and hence it is called as the recessive factor.
→In the presence of dominant unit factor recessive unit factor can not express itself and hence named law of dominance.
3) Law of segregation :-
→During gamete formation ; the unit factors of a pair segregate randomly and transfer inside different gamete. Each gamete receives only one factor of a pair ; so gametes are pure for a particular trait. It is known as conclusion of purity of gametes or segregation.
→The Segregation is essential during the meiotic division in all sexually reproducing organism.
→Nondisjunction maybe exception of this law.

Gregor Mendel, through his work on pea plants, discovered the fundamental laws of inheritance. He deduced that genes come in pairs and are inherited as distinct units, one from each parent. Mendel tracked thesegregation of parental genes and their appearance in the offspring as dominant or recessive traits.
