Detailed explanation-1: -The chromosomes in a homologous pair each have the same genes in the same order, but there may be variation between them, resulting in different alleles. Some of the variants in these alleles might have functional implications while others will not.

Detailed explanation-2: -Answer and Explanation: The correct answer is option C. The chromosomes in a homologous pair originate from both parents of the offspring.

Detailed explanation-3: -Homologous chromosomes contain the same genes, but potentially different alleles.

Detailed explanation-4: -Homologous chromosomes are matched pairs containing genes for the same traits in identical locations along their length. Diploid organisms inherit one copy of each homologous chromosome from each parent; all together, they are considered a full set of chromosomes.

Detailed explanation-5: -So, the correct answer is ‘Same chromosome, same gene, different allele in the same order’.
