Vedclass · Answer

(B) The egg of a frog is mesolecithal,meaning it contains a moderate amount of yolk. The yolk is not distributed evenly but is concentrated heavily in the vegetal pole. During cleavage,the presence of this dense yolk in the vegetal hemisphere acts as a physical barrier,which slows down the rate of cell division compared to the animal pole. Consequently,the cleavage furrows cannot pass through the vegetal pole as quickly or as completely as they do through the animal pole,resulting in unequal holoblastic cleavage rather than equal holoblastic cleavage.
