    Vegetative propagation is practiced for growing some types of plants because of following advantages:
    1. It is used to grow a plant in which viable seeds are not formed or very few seeds are produced such as Orange, Banana, Pineapple.
    2. It helps to introduce plants in new areas where the seed germination fails to produce mature plant due to change in environmental factors and the soil.→ It is more rapid, easier and cheaper method.
    3. By this method a good quality of a race or variety can be preserved.

  2. Importance of DNA copying in reproduction is:- 1) It contains information about inheritance from parents to offspring. 2) It codes for proteins required by an individual. 3) If DNA is not copied during reproduction, correct proteins will not be formed and the structure of the individual will be entiRead more

    Importance of DNA copying in reproduction is:-
    1) It contains information about inheritance from parents to offspring.
    2) It codes for proteins required by an individual.
    3) If DNA is not copied during reproduction, correct proteins will not be formed and
    the structure of the individual will be entirely different.
    4) Errors in DNA copying will lead to evolution.
    5) It makes the organism look similar to each other.
