Detailed explanation-1: -Homologous chromosomes are made up of chromosome pairs of approximately the same length, centromere position, and staining pattern, for genes with the same corresponding loci. One homologous chromosome is inherited from the organism’s mother; the other is inherited from the organism’s father.

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 have alleles on the same genes located in the same loci. Heterologous chromosomes have alleles on different genes. Pairs up during meiosis. Does not pair up during meiosis. Gene exchanges may occur at synapses.

Detailed explanation-4: -Pairs of similar chromosomes are called homologous chromosomes. During meiosis, the pairs of homologous chromosome are divided in half to form haploid cells, and this separation, or assortment, of homologous chromosomes is random.

Detailed explanation-5: -The pairs of autosomes are called “homologous chromosomes.” Homologous chromosomes have all of the same genes arranged in the same order, but there are small differences in the DNA letters of the genes.
