Question

Match the following:

  1. a-1, b-2, c-3
  2. a-3, b-1, c-2
  3. a-2, b-3, c-1
  4. a-3, b-2, c-1

hintHint:

  • Fertilization is a step of reproduction.
  • Crossing over occurs during cell division.
  • No two individual appear same due to variation.

The correct answer is: a-3, b-1, c-2


    • The correct option is a-3, b-1, c-2
    • Fertilization is a part of sexual reproduction. The process involves a male and a female gamete. The fusion of the haploid gametes results in the formation of a diploid zygote this process is called as fertilization.
    • Crossing over is a step in meiosis. Meiosis is a cell division which results in the formation of haploid gametes. During the process, the homologous chromosomes exchange genetic materials.
    • Variation is the difference in genetic make up of individuals within a species. This is the reason why even identical twins have different genetic makeup.
