Vedclass · Answer

(D) Sexual reproduction is characterized by the fusion of male and female gametes,the formation of zygote,embryogenesis and variations. These events are grouped into three distinct stages:$1$. Pre-fertilisation events: These include all the events prior to the fusion of gametes,specifically gametogenesis (formation of gametes) and gamete transfer.$2$. Fertilisation: This is the actual process of the fusion of male and female gametes to form a diploid zygote.$3$. Post-fertilisation events: These include events that occur after the formation of the zygote,such as the development of the zygote and embryogenesis.Therefore,the correct sequential order is Pre-fertilisation $\rightarrow$ Fertilisation $\rightarrow$ Post-fertilisation,which corresponds to $I \rightarrow II \rightarrow III$.

$(B)$ Crow	$(2)$ $140 \text{ years}$
$(C)$ Parrot	$(3)$ $15 \text{ years}$

Events in the sexual reproduction:
$I.$ Pre-fertilisation
$II.$ Fertilisation
$III.$ Post-fertilisation
The sequential order of their occurrence is:
