Every somatic cell in a human contains 23 pairs of chromosomes. Pairs 1 to 22 are autosomes, while pair 23 are the sex chromosomes. The pairs are described as homologous chromosomes. Answer the following questions about homologous chromosomes: Where do the chromosomes that make up each pair come from? Explain how the terms homologous chromosomes and sister chromatids are different. In genetic males, there is one pair that is not homologous. Identify the pair and explain why.
