What is the pattern of cleavage in amphibians?

In amphibians, the pattern of cleavage is typically holoblastic and unequal. This means that the entire egg undergoes cleavage, but the divisions are not equal; the animal pole (where the embryo will develop) divides more rapidly than the vegetal pole. The resulting cells, or blastomeres, vary in size, with smaller cells forming at the top and larger ones at the bottom. This unequal cleavage contributes to the organization and differentiation of the developing embryo.
