What term describes corresponding sets of chromosomes, one from each parent?

• A. The two identical copies of a chromosome in a somatic cell
• B. The chromosome carrying the same gene for the same trait
• C. Corresponding sets of chromosomes, one set from each parent
• D. Any pair of chromosomes with no identical genes

Answer: (C)

Homologous chromosomes are the paired chromosomes that carry the same genes in the same order, with one member inherited from each parent. In diploid organisms like humans, you have one homolog from the mother and one from the father for each chromosome type, and they pair up during meiosis I. They may carry different versions of a gene (alleles), which is where variation comes from when they are separated into gametes. They are not the same as sister chromatids, which are identical copies of a single chromosome produced during DNA replication and held together at the centromere. So the idea described is homologous chromosomes.
