If all 8 blastomeres of mammalian morula are separated, then what will happan ?

Options

A. Die immediately
B. Incomplete embryo developed
C. 8 identical embryo developed
D. Only one complete embryo developed and remaining blastomeres will be destroyed

Answer

**Step-by-Step Solution:**

1. **Understanding the Morula Stage**: The morula stage in mammalian development occurs after several rounds of mitotic divisions of the zygote, leading to a solid ball of cells known as blastomeres. In this case, we have 8 blastomeres.

2. **Definition of Blastomeres**: Blastomeres are the individual cells formed during the cleavage stage of embryonic development. Each of these cells is capable of developing into a complete organism due to their totipotent nature.

3. **Concept of Totipotency**: Totipotency refers to the ability of a single cell to develop into a fully functional organism. In the context of the morula, each of the 8 blastomeres retains this ability.

4. **Separation of Blastomeres**: If all 8 blastomeres of the morula are separated, each blastomere can develop independently because they are totipotent. This means that instead of dying or forming an incomplete embryo, each separated blastomere has the potential to develop into a complete and viable embryo.

5. **Outcome of Separation**: Since each blastomere can develop into a complete organism, the result of separating the 8 blastomeres will be the formation of 8 identical embryos. This is because they originate from the same zygote and share the same genetic material.

6. **Conclusion**: Therefore, if all 8 blastomeres of the mammalian morula are separated, the correct outcome is that 8 identical embryos will develop.

**Final Answer**: 8 identical embryos will develop.
