PATHOLOGY

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: -Homologous chromosomes are chromosomes which contain the same genes in the same order along their chromosomal arms.

Detailed explanation-3: -Answer and Explanation: Alternative forms of a gene having the same position on a pair of homologous chromosomes is called an allele.

Detailed explanation-4: -Homologous chromosomes carry the same sequence of genes but not necessarily the same alleles of those genes. Diploid nuclei have pairs of homologous chromosomes. Haploid nuclei have one chromosome of each pair.

Detailed explanation-5: -Homologous chromosomes contain the same genes in the same locations, but the versions of these genes can be different. These different versions are called alleles, meaning the answer is true. Each person has two copies of each chromosome, one of which came from their mother and the other from their father.
