    In India, we find mangoes with different flavours, colours, fibre content, sugar content and even shelf life. The large variation is on account of:

    A)  species diversity             

    B)        induced mutations

    C)        genetic diversity

    D)        hybridization

    Correct Answer: C

    Solution :

                    Genetic diversity is the basis of formation of new species of mangoes with different flavour, colour, fibre content, sugar content and even self-life. The greater is the genetic diversity of a species, the higher is its efficiency to adapt. The variation in the constitution of genes of a species constitute genetic diversity of that species. The variations in the gene complex of a species allows it to live in its particular habitat. It is only because of this genetic diversity that natural selection can operate in the process of evolution. The species diversity of any area is determined by various species that live there when the process of mutation (sudden heritable change in genes) can be achieved by artificial means, it is called induced mutation. Hybridization is the production of one or more hybrid organisms by the mating of genetically different parents.
