(B) The classification of eggs based on the amount of yolk is as follows:$1$. $Alecithal$: Eggs with no yolk (e.g.,placental mammals).$2$. $Microlecithal$ (or $Oligolecithal$): Eggs with a very small amount of yolk (e.g.,$Hydra$,sea urchin,$Amphioxus$,marsupials,and eutherians).$3$. $Mesolecithal$: Eggs with a moderate amount of yolk (e.g.,amphibians).$4$. $Polylecithal$ (or $Macrolecithal$): Eggs with a large amount of yolk (e.g.,birds and reptiles).Therefore,eggs containing a very small amount of yolk are called $Microlecithal$ eggs.
