问:我们计划生育技术服务站常遇到一些妇女询问“我的血型是O型,我丈夫的是AB型,胎儿会不会出现ABO溶血症?”那么,ABO溶血症究竟是怎么一回事呢? 高锦声教授: 血型是由基因所决定的。人类的ABO血型基因,位于第9对染色体上。在遗传学上,ABO血型抗原和遗传基因使用的符号相同:A、B、O。A和B基因属于显性基因,O基因属于隐性基因,它们同样严格按照孟德尔分离与自由组合的规律遗传。据目前研究所知,人类可以有AA,AO,BB,BO,AB及OO Q: We often encounter at the family planning service station some women asking, “My blood type is O type, my husband is type AB, the fetus will be ABO hemolytic disease?” So, ABO hemolytic disease is how the matter Professor Gao Jinsheng: Blood type is determined by the gene. The human ABO blood group is located on chromosome 9. Genetically, ABO blood group antigens and genes use the same symbols: A, B, O. A and B genes are dominant genes, O genes are recessive genes, they are also strictly in accordance with the rules of Mendelian separation and freedom of inheritance. According to the current research, humans can have AA, AO, BB, BO, AB and OO
