Robertsonian translocation is a type of translocation caused by breaks at or near the centromeres of two acrocentric chromosomes. The reciprocal exchange of parts gives rise to one large metacentric chromosome and one extremely small chromosome that may be lost from the organism with little effect because it contains few genes. The resulting karyotype in humans leaves only 45 chromosomes, since two chromosomes have fused together. This has no direct effect oRobertsonian translocation: Definition, symptoms, and more,227· Trisomy 13 can cause physical abnormalities, such as extra fingers or toes, an opening in the lip, or cleft lip, or an opening in
