In some cases, blastomere can produce a complete embryo. The cleavage will be?
Correct answer: D. Radial and indeterminate
- A. Spiral and determinate
- B. Spiral and indeterminate
- C. Radial and determinate
- D. Radial and indeterminate
Explanation
Option A: In spiral cleavage the division of cells in the developing embryo is in a spiral manner and blastomeres are not formed. Also, a complete embryo is not formed in determinant cleavage thus this option is incorrect.Option B: Though indeterminate cleavage results in a complete embryo, it will not have blastomeres as it will be in spiral manner thus this option is incorrect.Option C: Though radial cleavage produces blastomeres, determinant ones don't produce a complete embryo hence this option is incorrect.Option D: This is the correct option because the radial cleavage will produce blastomeres and indeterminate means that a complete embryo will be formed.
