Holoblastic cleavage

Vedclass · Answer

(A) Cleavage is the series of rapid mitotic divisions of the zygote. When the cleavage furrow passes through the entire egg,dividing it into complete blastomeres,it is known as $Holoblastic$ $cleavage$. This type of cleavage is typically observed in isolecithal eggs (e.g.,human eggs) where the yolk is sparse and evenly distributed. $Meroblastic$ $cleavage$ occurs in eggs with a large amount of yolk,where the division is restricted to a small portion of the cytoplasm. Therefore,the correct option is $A$.
