Vedclass · Answer

(B) The pattern of cleavage in a frog's egg is holoblastic and unequal.This occurs because the frog's egg is mesolecithal (containing a moderate amount of yolk concentrated at the vegetal pole).The cleavage furrow passes through the entire egg (holoblastic),but the presence of yolk at the vegetal pole slows down the process,resulting in unequal-sized blastomeres: smaller cells called micromeres at the animal pole and larger cells called macromeres at the vegetal pole.
