Which type of chromosomes are identical in size, appearance, and contain the same genes?

• A. Sex Chromosomes
• B. Homologous Chromosomes
• C. Autosomes
• D. Chromatids

Answer: (B)

Homologous chromosomes are pairs of chromosomes in a diploid organism that are similar in size and shape and contain the same genes at corresponding loci. Each homologous chromosome in the pair comes from one parent and carries the same type of genetic information, although the alleles (versions of a gene) may differ. This similarity allows for proper pairing during meiosis, which is crucial for sexual reproduction and genetic diversity. In diploid organisms, one set of chromosomes is inherited from the mother (maternal) and the other set from the father (paternal). Homologous chromosomes play a vital role in ensuring that offspring inherit a combination of traits from both parents. While sex chromosomes also have a role in determining biological sex and can be compared, they are not identical in appearance or gene content across all individuals, especially in species with differing sex chromosome configurations. Autosomes refer to the chromosomes that are not involved in determining sex and can be homologous as well; however, the term "autosome" encompasses all non-sex chromosomes regardless of whether they are paired with homologs. Chromatids, on the other hand, are identical strands of DNA formed after DNA replication. They are not distinct chromosomes in the homologous sense but are instead identical halves of
