Give the basic features of the mechanism of inheritance.

Answers (1)

Features of mechanism of inheritance are following:
(i) Genes control characters.
(ii) Genes are found on chromosomes
(iii) Genes may be of two or more forms. One form may be dominant while other is recessive.
(iv) Each parent has a couple of genes for each characteristic on a chromosome.
(v) Zygote carries characteristics of both the parents which are inherited through the genes. Zygote is formed when a male gamete fuses with the female gamete during fertilization. Zygote has full set of genes. This gives variation from one generation to next generation.
(vi) The off-springs inherit two genes (or a pair of genes) for each trait from its parent’s characters.
