Pattern of cleavage

Vedclass · Answer

(B) The amount and distribution of yolk in an egg significantly influence the pattern of cleavage during early embryonic development.$1$. Yolk acts as a physical barrier to the cleavage furrow.$2$. In eggs with little yolk (isolecithal),cleavage is holoblastic (complete).$3$. In eggs with a large amount of yolk (telolecithal or centrolecithal),cleavage is meroblastic (incomplete) because the furrow cannot penetrate the dense yolk.Therefore,the distribution of yolk determines whether the cleavage will be holoblastic or meroblastic.

Variations in the amount and distribution of yolk in an egg affect which of the following?
