Somatogamy is the fusion of-

Options

A. Two vegetative/somatic cell, of different strain/genotypes to form dikaryotic cell
B. Sperm with egg
C. 2 somatic cell having identical strain
D. egg with egg

Answer

**Step-by-Step Solution:**

1. **Understanding Somatogamy**: Somatogamy refers to a type of sexual reproduction where two somatic cells (which are non-reproductive cells) fuse together. This process is crucial in certain organisms, particularly in fungi and some algae.

2. **Identifying the Cells Involved**: In somatogamy, the cells that undergo fusion are typically vegetative and somatic cells from different strains or genotypes. This means that the cells are not identical and come from different genetic backgrounds.

3. **Formation of Dicharotics**: The fusion of these two different somatic cells leads to the formation of a structure known as a dicharotic. This structure is a result of the genetic material from both parent cells combining.

4. **Clarifying Common Misconceptions**: It is important to note that the fusion of two identical somatic cells or the fusion of reproductive cells (like egg and sperm) is not classified as somatogamy. Instead, somatogamy specifically involves the fusion of two different somatic cells.

5. **Conclusion**: Therefore, the correct answer to the question "Somatogamy is the fusion of-" is the fusion of two vegetative and somatic cells of different strains or genotypes.

**Final Answer**: Somatogamy is the fusion of two vegetative and somatic cells of different strains or genotypes.
