Suppose you're looking through a microscope and you see an exchange of chromosomes segments between chromosome pair 7 and chromosome pair 15 this condition is an example of?

During prophase (in meiosis) homologous chromosomes sometimes exchange parts, in a process called crossing over. In most chromosomes, at least one exchange between each homologous pair occurs during each meiotic cell division. In the end, the chromosomes that each haploid daughter cell receives will have different sets of alleles than the chromosomes of the parent cells.
Crossing over: exchange of parts of DNA in a homologous chromosome in the area where they come in contact with each other. Then this chromosome splits, during meiosis, to form a daughter cell (gamete) with a haploid number of chromosomes. During fertilization, the two gametes fuse into one cell containing now a diploid number of chromosomes. This process leads to genetic diversity and variation.
