Question

3.Explain why a life cycle that includes meiosis must also include fertilization. What is the advantage of such a life cycle?

Answer 1

Question

3. The process of meiosis reduce the chromosomes number to half as compare to the parent cell and produce cells known as gametes. Whereas the fertilization is the process of fusion of haploid gametes to restore the chromosome number as that of parent cell.Both  meiosis and fertilization alternate in sexual life cycle. Therefore, fertilization is required in the meiotic cells to restore the chromosome number as of parent cell and meiosis is required to produce gamete cells so that chromosomes number will remain same from one generation to another. The advantage of this life-cycle include the restoration of chromosome number in both germ cells and zygote cell.
