Question

Pattern of cleavage in egg of frog is

• A. Meroblastic
• B. Holoblastic unequal
• C. Holoblastic equal
• D. All the above

Answer 1

The correct option is B Holoblastic unequal

The frog egg contains a large amount of yolk and is telolecithal in nature. The egg is divided into two hemispheres: one is the animal pole and second is the vegetal pole.

The nucleus and the yolk is concentrated in the animal pole.

In the frog, the cleavage is of holoblastic unequal type because of a large amount of yolk present. It acts as a barrier in the division of the cells.

So, the correct option is 'Holoblastic unequal'
