Given the basic features of the mechanism of inheritance.

Explanation

Inheritance is the transmission of genetically controlled characteristic (traits) from one generation to the next. The basic features of mechanism of inheritance are following:
(i) Each character is controlled by a gene. These genes are present on DNA. DNAs in turn are present in the form of chromosomes. Every trait is present in pairs, i.e. alleles. Out of a pair of contrasting traits, one is present on a particular chromosome and another is present on another chromosome. This ensures that one trait goes to one gamete and another goes to another gamete, when gametes are formed. This forms the basis of the Law of Segregation, as proposed by Mendel
(ii) There may be two or more forms of a gene. One form may be dominant while other is recessive.
(iii) Genes are present on chromosomes during fertilization.
(iv) Each parent possesses a pair of genes for each characteristic on a chromosomes.
(v) When a male gamete fuses with the female gamete during fertilization, they make a new cell called zygote with a full set of genes. This zygote carries characteristics of both the parents which are inherited through the genes.
(vi) The offsprings inherit two genes (or a pair of genes) for each trait from its parents characters. The trait shown by the offsprings in first of enation dominant.
