Frog embryo cleavage

WebMay 22, 2024 · Cleavage or segmentation: In frog, the division is complete but the cells formed are unequal. So, the cleavage is called holoblastic but unequal. The first division is vertical and divides the zygote into two blastomeres. The furrow extends from animal pole to the vegetal pole (lower end).
