Vedclass · Answer

(C) Holoblastic cleavage refers to the complete division of the egg into blastomeres. This occurs in eggs with little or no yolk (isolecithal) or moderate amounts of yolk (mesolecithal). $1$. $Hydra$ (Cnidarian) undergoes holoblastic cleavage. $2$. $Amphioxus$ (Cephalochordate) undergoes holoblastic cleavage. $3$. $Frog$ (Amphibian) undergoes holoblastic cleavage. $4$. $Hen$ (Bird) has telolecithal eggs with a large amount of yolk,which restricts cleavage to a small disc on the surface (meroblastic cleavage). Since the question asks for an example of holoblastic cleavage,and $Hydra$,$Amphioxus$,and $Frog$ all exhibit this,the question is likely referring to a specific context or may have multiple correct answers. However,in many standard textbooks,$Frog$ is the classic example used to illustrate holoblastic cleavage.
