It is possible for humans with balanced chromosome translocations to have normal children. Chromosomes are a number of long, darkly colored strips in the nucleus of human cells that have the main carriers of intracellular genetic material. There are mainly 46 chromosomes in the human body, and their number and structure are relatively fixed. Balanced translocation of chromosomes is when two chromosomes undergo breakage at the same time, and the segments exchange positions before reassembling to become structurally rearranged chromosomes. It only involves a change in the position of the chromosomes, but it does not affect the increase or decrease of the segments, and there is no loss of genetic material. So there is a probability of having a normal child. Although it is possible to have a normal child with a balanced chromosome translocation, there may be cases such as habitual abortion, which leads to a decrease in the fertility rate, and genetic counseling is recommended.
