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.
Detailed explanation-2: -Each pair consists of chromosomes of the same size and shape, and they also contain the same genes. The chromosomes in a pair are known as homologous chromosomes.
Detailed explanation-3: -Homologous chromosomes correspond to the chromosomes present on the same pair in contrast to non-homologous chromosomes where they are found on different pairs. Number of chromosomes in homologous pairs are based on the ploidy of that entity.
Detailed explanation-4: -Homologous chromosomes are chromosomes that share: The same structural features (e.g. same size, same banding patterns, same centromere positions) The same genes at the same loci positions (while the genes are the same, alleles may be different)
