Suppose a human egg is fertilised by a sperm. If, immediately after fertilisation,the zygote is divided into two separate cells, then this process would result in
Correct answer: C. Identical twins
- A. Fragmentation
- B. Fraternal twins
- C. Identical twins
- D. Parthenogenesis
Explanation
The correct answer is identical twins. When a single zygote divides into two separate cells after fertilization, it results in identical twins, as both cells develop into genetically identical individuals. Fragmentation is unrelated to human zygote division, as it pertains to organisms that reproduce asexually. Fraternal twins result from two different eggs being fertilized by different sperm. Parthenogenesis is an asexual reproduction process that does not involve fertilization and is not relevant to human reproduction.
