What term describes pairs of matching chromosomes?

• A. Non-matching chromosomes
• B. Chromosome segments that code for traits
• C. Pairs of matching chromosomes
• D. Sex-determining chromosomes

Answer: (C)

Pairs of homologous chromosomes are the matched copies that come from each parent. They are similar in size and shape and carry the same genes in the same order, though they may have different alleles. Describing them as “pairs of matching chromosomes” directly captures this idea, which is why it’s the best answer. The other options don’t fit: non-matching chromosomes aren’t a true pair, chromosome segments that code for traits refer to genes rather than whole chromosomes, and sex-determining chromosomes are a specific subset involved in sex determination, not the general concept of chromosome pairing.
