Chromosomes that are the same size and shape and carry the same genes are called

• A. Autosomes
• B. Sister chromatids
• C. Homologous chromosomes
• D. Chromatid pairs

Answer: (C)

Chromosomes that come as a matching pair in diploid organisms are homologous chromosomes. One member of the pair comes from each parent, and they are similar in length and structure, with genes located at the same positions along their lengths. They may carry different versions of those genes (alleles), which is what can lead to genetic variation when they are shuffled during meiosis. This is different from sister chromatids, which are two identical copies of the same chromosome that are produced during DNA replication and held together at the centromere. They are not a paired set from different parents. Autosomes refer to all the non-sex chromosomes, but the statement here specifically describes a homologous pair.
