Question

Cleavage found in mesolecithal egg is

• A. Holoblastic and equal
• B. Holoblastic and unequal
• C. Meroblastic
• D. Discoidal

Answer 1

The correct option is B Holoblastic and unequal

In the absence of a large concentration of yolk, four major cleavage types can be observed in isolecithal cells (cells with a small even distribution of yolk) or in mesolecithal cells (moderate amount of yolk in a gradient) - bilateral holoblastic, radial holoblastic, rotational holoblastic and spiral holoblastic cleavage.
