MENDEL'S LAWS OF INHERITANCE :
1. Law of Dominance :
Out of a pair of contrasting characters present together, only one( called the dominant character) is able to express itself while the other remains suppressed. The recessive or the suppressed character can express only when the pair consists of both recessives.
2. Law of Segregation (or Law of purity of gametes) :
The two alleles of a gene when present together in a hetero-zygote state, do not fuse or blend in anyway, but remain distinct and segregate during meiosis or in the formation of gametes so that each meiotic product or gamete will carry only one of them.
3. Law of Independent Assortment :
When two pairs of traits are combined in a hybrid, segregation of one pair of characters is independent of the other pair of characters.
