Now looking at the given options if we have to tell the stages from early to late, let's look at each of the option and then we will roll out.
00:09
Now looking at the first option, it says egg to cleavage to zygote to fertilization to gastrula to embryo and then to the blastula stage.
00:27
Now here we need to understand that the egg will not first undergo.
00:32
Cleavage.
00:34
It has to first get fertilized so this option is absolutely wrong.
00:38
Looking at the second option we again have egg undergoing cleavage then forming zygote then forming the embryo then there's fertilization to form the blastula and then there's formation of the gastrilla.
00:57
Like i've said this is not the sequence because the formation of zygote is because of diffusion of gametes and that's by the process.
01:05
Of fertilization.
01:06
So option b is also wrong.
01:08
Now looking at option c, they're given cleavage, formation of the zygote wrong.
01:14
Then there's formation of the gastrilla.
01:18
Again absolutely wrong...
