MCQ
A universal phenomenon in sexually reproducing organisms is the formation of:
  • A
    Embryo
  • ✓
    Zygote
  • C
    Egg
  • D
    Gametes
✓

Answer

Correct option: B.
Zygote
During sexual reproduction in all eukaryotes $($plants and animals$)$ the male and female gametes fuse leading to the formation of zygote.
Generally, gamete formation is not a part of asexual reproduction.
But in haploid parthenogenesis, a rare form of parthenogenesis that occurs in a few species of bees, nematodes, and plants, offspring develop from haploid eggs to produce haploid adults.
We still consider this a type of asexual reproduction as gametes are formed but there is no fusion of gametes to form zygote, .
