For a given character, a gamete is always

Options

A. Homozygous
B. Pure
C. Hybrid
D. Heterozygous

Answer

To solve the question "For a given character, a gamete is always...", we need to understand the concept of gametes and their genetic composition.

### Step-by-Step Solution:

1. **Understanding Gametes**: Gametes are reproductive cells (sperm and egg) that carry genetic information. Each gamete is produced through a process called meiosis.

2. **Alleles in Gametes**: During meiosis, the alleles for a given trait segregate. This means that if an organism has two alleles for a trait (for example, Aa), the gametes produced will receive only one of these alleles (either A or a).

3. **Pure vs. Hybrid**:
- A **homozygous** organism has two identical alleles for a trait (e.g., AA or aa).
- A **heterozygous** organism has two different alleles for a trait (e.g., Aa).
- A **pure** trait refers to an organism that is homozygous for that trait.
- A **hybrid** refers to an organism that is heterozygous.

4. **Law of Purity of Gametes**: According to Mendel's second law, known as the Law of Segregation, each gamete carries only one allele for each gene. This means that gametes are "pure" for the traits they carry.

5. **Conclusion**: Since each gamete contains only one allele for a given character, we can conclude that for a given character, a gamete is always **pure**.

### Final Answer:
For a given character, a gamete is always **pure**.
