So, life begins when fertilization occurs.
00:08
Okay, what is fertilization? fertilization is a sequence of events.
00:16
And it occurs when the ovum, also known as secondary usite, gets fertilized with the help of sperm.
00:30
So when the ovum and sperm gets fused, it is known as fertilization.
00:35
So sperm is actually contributed by the male and opharm is contributed by the female.
00:47
Okay.
00:48
So what happens here is after they are fertilized, they actually, they are chromosomes.
00:57
The chromosomes mix or mingle.
01:04
And each all, both of them make a single set.
01:09
Which is known as zygote and that's when the life new life begins okay when fertilization occurs new life begins and when the sperm cell of the human male and when it meets the o -firm cell of the female human -female the union takes place and zygote is formed this marks the beginning of the new life okay and in zygote both the the chromosomes are kept or we can say enclosed okay because those were actually mingled when the fertilization was occurring so the biological contribution of a female begins with the help of oogenesis okay what is ogenesis this is the process of production of the secondary usite or oven.

Okay? so it begins in the ovaries of the females...
