Question

Is there a size difference between the animal and vegetal blastomeres in a 32 cell stage frog embryo?

Answer 1

Yes, there is a size difference in animal and vegetal region, vegetal region have larger sized blastomeres compare to animal region

Explanation:- Cleavage of a frog egg, However, because of the vegetally placed yolk, this cleavage furrow in amphibian eggs is not actually at the equator, but is displaced toward the animal pole. It divides the frog embryo into four small animal blastomeres (micromeres) and four large blastomeres (macromeres) in the vegetal region.
