AIIMS 2019 Biology Linkage and Recombination MCQ Question

Genes on the same chromosome can be homologous, meaning they occupy corresponding positions on homologous chromosomes and can have different alleles. Option A, "linked," refers to genes that are physically close on the same chromosome and tend to be inherited together, but not all genes on the same chromosome are linked. Option C, "autosomes," refers to non-sex chromosomes and does not specifically describe the relationship between genes. Option D, "identical alleles," implies that the alleles are the same, which is not necessarily true for genes on the same chromosome, as they can have different alleles.
