The correct Answer is:
**Step-by-Step Solution:** 1. **Understanding the Question**: The question asks about a type of egg development where future organs are already differentiated into specific regions before cleavage begins. 2. **Analyzing the Options**: - **Regulated Development**: This type of development allows for the removal of a cell from an early embryo, and the remaining cells can still form a complete organism. This does not match the description given in the question. - **Mosaic Development**: In this type of development, if one or more cells are destroyed in a two-cell or one-cell embryo, only the remaining cells will develop into part of the organism. This aligns with the idea of future organs being demarcated before cleavage. - **Gynogenesis**: This refers to a type of reproduction where the embryo develops with only maternal chromosomes. This is not relevant to the question. - **Indeterminate Development**: This is a type of development where the fate of the cells is not fixed early on, which does not fit the description provided. 3. **Identifying the Correct Answer**: Based on the analysis, the correct answer is **Mosaic Development**. This type of development indicates that specific regions of the embryo are already predetermined, even before cleavage begins. 4. **Conclusion**: Therefore, the answer to the question is **Mosaic Development**. ---
