The law of segeration of characters is also called the law of purity of gametes because

Options

A. Gametes have only one of the two alleles for each character
B. Gametes cannot be contaminated
C. Gametes are very different type of cells
D. It was just another name adopted accidently

Answer

**Step-by-Step Solution:**

1. **Understanding the Law of Segregation**: The law of segregation, proposed by Gregor Mendel, states that during the formation of gametes (sperm and egg cells), the two alleles for a trait segregate from each other so that each gamete carries only one allele for each trait.

2. **Definition of Gametes**: Gametes are reproductive cells that carry genetic information. In diploid organisms, these cells contain only one copy of each chromosome, and thus only one allele for each gene.

3. **Mendel’s Experiment**: Mendel conducted experiments using garden peas, where he crossed plants with different traits (e.g., tall vs. dwarf). He observed that in the F1 generation, all offspring exhibited the dominant trait (tall), but when these were crossed, the F2 generation showed a 3:1 ratio of dominant to recessive traits.

4. **Purity of Gametes**: The term "purity of gametes" refers to the fact that each gamete produced during meiosis contains only one allele for each gene. This means that the gametes are "pure" in the sense that they do not carry both alleles for a trait.

5. **Conclusion**: Therefore, the law of segregation is also called the law of purity of gametes because gametes have only one of the two alleles for each character. This ensures that when gametes combine during fertilization, the offspring can inherit one allele from each parent.

**Final Answer**: The law of segregation of characters is also called the law of purity of gametes because **gametes have only one of the two alleles for each character** (Option 1).
