Question
Match the following:
- a-1, b-2, c-3
- a-3, b-1, c-2
- a-2, b-3, c-1
- a-3, b-2, c-1
Hint:
- 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.
