MCQ
The term ‘clone’ cannot be applied to offspring formed by sexual reproduction because:
  • ✓
    Offspring do not possess exact copies of parental $\text{DNA.}$
  • B
    $\text{DNA.}$ of only one parent is copied and passed on to the offspring.
  • C
    Offspring are formed at different times.
  • D
    $\text{DNA.}$ of parent and offspring are completely different.
✓

Answer

Correct option: A.
Offspring do not possess exact copies of parental $\text{DNA.}$
Gametogenesis takes place through meiosis and crossing over takes place during meiosis. Crossing over is responsible for some alteration in genotype. Moreover, fertilization results in gene pools from two different individuals and thus zygote has a somewhat different genotype than both the presents. Hence, the term clone cannot be applied to offspring formed by sexual reproduction.
