00:01 Hi, the given question from fertilization and the overall process.

00:17 As we know that, fertilization, it means fusion of haploid male and female gametes result in the formation of zygote.

00:47 So it is a fusion of sperm and ova.

00:53 Fusion of sperm plus ova this is called fertilization and ovum nuclei and is unaffected by presence of yoke which is formed much later during the embryonic development in the humans fertilization and zygote formation depend on sperm mortality and viability acrosomal reaction and synchronized release of ovarian from the graphian follicle so that in the embryological process transforms single cell as a zygot into a hollow structure is spherical multicellular multicellular blastular a referred to as cleaves.

02:35 In this process, daughter cells produced by cleaves in zygote are termed as blastomere.

02:55 Also, now, in fertilized or in fertilized egg or activated egg, undergoes repeated cell division rapidly producing a multicellular structure without changing its shape and all these rapid mitotic cell division are collectively called cleavage and also called segmentation due to the process of cleavage a single cell zygote through a successive mitrotic cell division changed into a complex multicellular structure and the cell produced as a result of cleavage are termed as blastomia now classific of the cleavage on the basis of amount of the yoke so that a scientist named balfour gave a law according to him rate of cleavage is is inversely proportional to the inversely proportional to the amount of yoke present in the egg so that the yoke presents in the egg disturbs the rate of the cleavage so rate of cleavage is slow in that part of egg in which amount of yoke is more and the rate of cleaves is faster in portion of egg in which yoke is lesser amount so it is it has two types one is complete or holoblastic complete or holoblastic in this complete or holoblastic when cleavage furrow pass through the egg called collectively so whole egg divide into the two part unequal holoblastic and equal holoblastic unequal holoblastic blastomere unequal size example is mesolacetal and example is human and also in equal holoblastic blastomere are of same size homolacithel isosithel is the example mammals eotheria metatheria and in next, in the myroblastic, or we can say that incomplete, cleaves doesn't occur in the part of egg where yolk is present...

Question

How does the yolk is causing an asymetry in the fertilized egg, and what are the types of eggs depending on the yolk ?
