In some cases the 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
If a blastomere is capable of producing a complete embryo, then the cleavage would be considered indeterminate. In indeterminate cleavage, each blastomere has the potential to develop into a complete organism, even if it is separated from the other blastomeres. Indeterminate cleavage is typically found in organisms that undergo early embryonic cell divisions, such as many invertebrates and some vertebrates. If a blastomere is capable of producing a complete embryo, the cleavage can be either radial or spiral. Radial cleavage occurs when the cell divisions are parallel or perpendicular to the animal-vegetal axis of the embryo, resulting in cells that are more or less symmetrical.
