The fate of each blastomere is foretold. The cleavage will be as____________?
Correct answer: D. Spiral and determinate
- A. Spiral and indeterminate
- B. Radial and indeterminate
- C. Radial and indeterminate
- D. Spiral and determinate
Explanation
Protostomes typically show spiral, determinate cleavage, meaning the fate of each early blastomere is largely fixed. Students may choose a because it includes spiral cleavage, but indeterminate cleavage is characteristic of radial deuterostome development rather than the stated pattern.
