Initially, the zygote splits along a longitudinal plane. The second division is also longitudinal, but at 90 degrees to the plane of the first. The third division is perpendicular to the first two and is equatorial in position.

Determinate cleavage is a type of cleavage that is mostly seen in arthropods, annelids, … WebCleavage is the rapid division of cells that happens after fertilisation during the early stages of embryogenesis. Here, puckering and furrowing of the plasma membrane happen in the fertilised eggs. The resultant nucleated cells formed due to cleavage are called blastomeres and the formation of blastula marks the conclusion of cleavage. danielsson fly reels reviews
