Transfer of genetic characters from individuals of one generation to those of a future generation through genetic descendants is known as heredity or inheritance.
Basic features of the mechanism of inheritance are as follows:-
1. Each character or trait is controlled by the pair of alleles.
2. In an organism having two alleles for the given trait, one is dominant (that expresses itself) and other is recessive (that may remain unexpressed), also defined as the law of dominance.
3. The two alleles of the trait get separated during the gametogenesis so that each gamete cell receives only one allele of each trait, and is defined as the law of segregation.
4. Each allele is transferred from one generation to another and remains unchanged.
5. Genes control the characters and are present on the chromosomes.
6. Two different forms of the gene will get separate at the time of gamete formation and are brought together in zygote.
