Most organisms that undergo sexual reproduction contain two types of cells in their body – haploid and diploid cells. Diploid cells are seen in most parts of the body and contain two copies of every chromosome. Therefore, they contain two genes to determine the sequence of nearly every RNA or protein. Haploid cells are usually male or female gametes formed as a result of meiosis and are seen in sexual organs. They contain only one complete set of chromosomes and are designed to fuse with another haploid gamete to produce a diploid zygote – with one paternal and one maternal set of chromosomes. Though they code for the same genes, their DNA sequences can vary slightly from one another. For instance, the paternal chromosome may contain the genetic information to result in antigen A being present on red blood cells, while the maternal chromosome may code for antigen B. These two antigens are similar in function, but differ from each other marginally in their amino acid sequence.

The word homo means equal. So from the name, we can understand that the chromosomes, which exchange there genetic matirials r equal in shape. ND we also know that, the homologous chromosomes bivalant, so that they can exchange there genetic materials. unequal chromosomes can't bivalant with each other. so they can't exchange there genetic material. so it is only the homologous chromosome which can exchange it's genetic material.
