Balanced translocation involves an exchange of genetic material between non-homologous chromosomes, but there is no loss or gain of genetic material. Therefore, balanced translocation generally has the least effect on the phenotype of the individual who carries it compared to Robertsonian and unbalanced translocations, which can cause partial or complete loss or duplication of genetic material, leading to significant phenotypic abnormalities.
