Chromosomes as well as genes occurs in pairs.

Answer

**Step-by-Step Solution:**

1. **Understanding the Statement**: The statement claims that chromosomes and genes occur in pairs. We need to determine if this statement is true or false.

2. **Chromosomal Theory of Inheritance**: According to the chromosomal theory of inheritance, chromosomes are the carriers of genetic information. This theory states that genes are located on chromosomes and that both chromosomes and genes occur in pairs.

3. **Types of Cells**:
- **Diploid Cells**: In somatic (body) cells, which are diploid, there are two sets of chromosomes (one from each parent). This means that chromosomes occur in pairs.
- **Haploid Cells**: In contrast, haploid cells (like gametes) contain only one set of chromosomes, meaning they do not have pairs.

4. **Genes and Alleles**: Each gene can have different forms known as alleles. In diploid organisms, each gene exists in two alleles (one from each parent), which means that genes also occur in pairs.

5. **Homologous Chromosomes**: The two alleles of a gene pair are located on homologous chromosomes, which are pairs of chromosomes that are similar in shape, size, and genetic content.

6. **Conclusion**: Since both chromosomes and genes occur in pairs in diploid cells, the statement is true.

**Final Answer**: The statement "Chromosomes as well as genes occur in pairs" is true.
