Do Organisms create Exact Copies of Themselves | The Importance of Variation | Types of Reproduction

What is the importance of DNA copying in reproduction?

Explain the importance of reproduction in organisms.

Consider the following statements for reproduction in organisms and choose the correct ones. I. The selection of the mode of reproduction depends on organism's habitat, physiology and complexity. II. Exact copies of organisms are produced via asexual reproduction. III. Gametes in sexual reproduction are produced in gonads, which are mesodermal in origin. IV. Sexual reproduction involves genetic recombination via crossing over between non-homologous chromosomes of both parents. Select the correct codes.
