If the segment that is lost is exchanged with a segment of another, non-homologous chromosome, it is a translocation.The formation of a chromosome translocation is a multistep process 3.Learn about chromosomal translocation, a common chromosomal mutation that involves the exchange of genetic material between two chromosomes.Mutations are often divided into those that affect a single gene, termed a gene mutation—also sometimes called a point mutation—and those that affect the structure of chromosomes, called a chromosomal mutation.When we think of mutations, most of us imagine point mutations, or regions within the DNA at which one to several bases are changed or deleted.
