Solution

The correct options are
A It requires gametes
B Fertilisation is a compulsory event
C Results in the formation of zygote
  • Fertilisation is the fusion of the male and the female gametes. It gives rise to zygote.
  • Zygote develops into an embryo which gets embedded in the mother's uterus.
  • Sexual reproduction results in the formation of new offsprings which have similarities and differences (variations) from both the parents.
  • Clones are identical (genetically) to the parent organism and are formed in case of asexual reproduction.
