Question

Which of the following feature is universal in all Sexually reproducing organisms? (1)Embryo formation 2)Gametic meiosis 3 Zygote formation (4) Pollen arof

Answer 1

Answer:

Zygote formation

If we talk about

(iv) it is wrong because pollen grain transfer does not happen in many plants due to external factors.

(ii) In gamete no meiosis takes place as it itself is the result of meiosis.

(i) Embryo formation is a step after zygote formation.

Answer 2

Male and female gametes fuse during sexual reproduction in all eukaryotes (plants and animals), resulting in the development of zygote.

Asexual reproduction does not usually include gamete creation.

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.

Although gametes are generated, there is no union of gametes to create a zygote, hence this is still considered asexual reproduction.

So, the correct answer is 'zygote'.
