An individual having similar unit factors of a character is

Options

A. Heterozygote
B. Homozygote
C. Dominant
D. Recessive.

Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks for the term that describes an individual with similar unit factors of a character. In genetics, unit factors refer to alleles, which are different forms of a gene.

2. **Identifying the Options**: The options provided are:
- Heterozygote
- Homozygote
- Dominant
- Recessive

3. **Defining the Terms**:
- **Heterozygote**: An individual with two different alleles for a particular gene (e.g., Aa).
- **Homozygote**: An individual with two identical alleles for a particular gene (e.g., AA or aa).
- **Dominant**: Refers to an allele that expresses its trait even in the presence of a different allele (e.g., A in Aa).
- **Recessive**: Refers to an allele that only expresses its trait when two copies are present (e.g., a in aa).

4. **Analyzing the Options**:
- Since the question specifies "similar unit factors," we need to find the term that represents having identical alleles.
- Heterozygote is incorrect because it refers to different alleles.
- Dominant and recessive refer to the expression of traits rather than the similarity of alleles.

5. **Conclusion**: The correct answer is **Homozygote**, as it describes an individual with similar unit factors (identical alleles) for a character.

**Final Answer**: Homozygote
