Answer 1

$\underline\bold{\huge{Answer! !}}$

Reproduction is the process by which living organisms produce new individuals similar to themselves. It basically involves the making copies of the blueprints of the body design.

Reproduction ensures continuity of life on earth.

Chromosomes in the cell contain the information for inheritance of features which are passed from generation to generation in form of DNA molecules.

so reproduction involves copying of DNA and other cell apparatuses. The copies will be similar to original and not identical.

This property is Variation which is the basis and necessary for evolution of living beings.

Variations help the species to withstand drastic environmental changes, thus save the species from becoming extinct and promotes its survival for a longer time.

Asexual Reproduction

1. A single parent is involved

2. Gametes not formed

3.Progeny is Identical to parent

Sexual Reproduction

1. Both Parents involved

2. Gametes are formed

3. Progeny is only genetically similar

to the parent but not identical

Asexual Reproduction is extremely useful as a mean of rapid multiplication. It is common in lower plants and animals.
