Chromosomes similar in size, shape, genes and gene sequences are

Options

A. Sister chromatids
B. Chromomeres
C. Homologous chromosomes
D. Parental chromosomes

Answer

To answer the question regarding chromosomes that are similar in size, shape, genes, and gene sequences, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Chromosomes**:
- Chromosomes are structures found in the nuclei of eukaryotic cells. They are composed of DNA and proteins.

2. **Identifying the Characteristics**:
- The question specifies chromosomes that are similar in size, shape, genes, and gene sequences.

3. **Evaluating the Options**:
- **Sister Chromatids**: These are identical copies of a chromosome that are formed during DNA replication. They are not considered homologous as they are exact duplicates of the same chromosome.
- **Chromomales**: This term is not commonly used in genetics and does not refer to a specific type of chromosome.
- **Homologous Chromosomes**: These are pairs of chromosomes, one from each parent, that are similar in size, shape, and genetic content. They contain the same genes at the same loci but may have different alleles.
- **Parental Chromosomes**: This term generally refers to the chromosomes inherited from the parents but does not specifically denote similarity in size, shape, or gene sequences.

4. **Conclusion**:
- Based on the evaluation, the correct answer is **homologous chromosomes**. These chromosomes are similar in size, shape, and gene sequences, with one chromosome inherited from each parent.

### Final Answer:
**Homologous chromosomes** are the chromosomes similar in size, shape, genes, and gene sequences.
