विकल्प

• Only part of egg divides

• Each blastomere has fixed developmental fate

Answer 1

Holoblastic cleavage refers to a complete division of the entire egg into smaller cells. This contrasts with meroblastic cleavage, where only a portion of the egg undergoes division. Human cleavage is holoblastic.
