Question

The fifth cleavage of the fertilized egg of frog results in the formation of

• A. 16 cells
• B. 48 cells
• C. 64 cells
• D. 32 cells

Answer 1

The correct option is D 32 cells

The cleavage in the frog is latitudinal. 1${}^{st}$ cleavage will result in the formation of 2 cells. The second will result in the formation of 4 cells (as the divisions are latitudinal) followed by 8 cells, 16 cells and the fifth cleavage will result in the formation of 32 cells which is called a blastomere.
Thus, the correct answer is option D.
