What is the common feature of cells classified as diploid?

• A. Contain only one set of chromosomes
• B. Are reproductive cells
• C. Have homologous chromosomes
• D. Contain specialized genes

Answer: (C)

Cells classified as diploid are characterized by having homologous chromosomes. In diploid organisms, such as humans, each cell contains two complete sets of chromosomes—one inherited from each parent. This means that for each chromosome, there is a corresponding homologous chromosome that carries the same genes but may have different alleles. This arrangement is crucial for sexual reproduction, as it allows for genetic diversity and proper segregation during meiosis, where diploid cells halve their chromosome number to produce haploid gametes. The presence of homologous chromosomes enables genetic recombination and variation, which are essential for evolution and adaptability. Cells with homologous chromosomes can participate in processes like crossing over during meiosis, further enhancing genetic diversity. This is a fundamental characteristic of diploid cells, distinguishing them from haploid cells, which contain only one set of chromosomes without homologous pairs.
