Question

Choose the correct option which explains why meiosis is required.

• A. Some cells can't undergo meiosis.
• B. Variation is necessary to sustain life.
• C. It is simpler than mitosis.
• D. To give identical offsprings

Answer 1

The correct option is B Variation is necessary to sustain life.

Meiosis results in a great variety of offsprings. Without meiosis, the entire human race would look alike. Meiosis is responsible for bringing about the recombination of the genes in maternal and paternal chromosomes, resulting in variation. A further variation is brought about by fertilisation of the female gamete by the male gametes.
