Now, crossing over is a very important process in cell division, okay? it's a very important process in cell division because actually it's an equivalent of recombinant dna, okay? because basically it's what you call an exchange of genetic material.
00:28
So crossing over is basically exchange of genetic material.
00:34
Material between two homologous chromosomes, okay? between two homologous chromosomes and resultant of this exchange of materials you would call a commonant chromosomes, a chromosome bearing the editing material from two sources.
01:06
So basically i'm trying also to say that the help around so crossing over crossing over brings about crossing over brings about what you call random shuffling random shuffling of genetic material during the process of phoenogamination so the genetic material shuffles randomly and we kind of give rise to individuals that are genetically distinct so what we have her nurse is genetically genetically distinct offspring okay or individuals from from parents okay in real life you can observe this from siblings okay parent a and parent b given rise to a child c right so this child c if you look at for your assembly, this child will be distinct from either of the parents because it's actually a recombinant molecule there, a recommend chromosome, right? but you see this kind of variation in genetics is important because actually it increases ability of our population to survive, so it increases survival rate of particular offspring.

Now, here for instance, i pull up an image here.
02:53
Let me pull up an image and then we observe what i really mean here.
03:15
So this is what i mean.
03:18
This is a perfect image for crossing over...
