人类血型除了大家熟知的 ABO 系统外、还有MNS、P、Rh 等十多个系统。经现代医学研究证明,这些血型系统都具有遗传性,并且有着一定的遗传规律。目前已知,体内负责遗传的物质,是细胞核内一种呈线状结构的染色体。父母亲的各种特性就是通过染色体传到子女身上的.沿染色体的长轴,又可分成许多小段,每一小段又都具有不同的遗传特性,这些小段称为基因.每条染色体上都含有很多基因.且都按严格的顺序排列在染色体上.人类的每一种血型系统,都是由细胞核内两条染色体某一特定位盔上的基因所组成的.组成某一血型系统的一对染色体,一条来自父亲,一条来自母亲。父母亲的细胞核内的染色体都
In addition to the well-known ABO system, there are more than 10 systems such as MNS, P and Rh. The modern medical research proves that these blood type systems are hereditary and have certain genetic rules. It is now known that the body responsible for the genetic material is a linear structure of chromosomes in the nucleus. The various characteristics of parents are transmitted to their children through the chromosomes along the long axis of the chromosome, but also can be divided into many small pieces, each have a different small section of the genetic characteristics of these small pieces called genes Each chromosome contains Many genes, and are arranged in strict order on the chromosomes of each human blood system, the nucleus by the two chromosomal helmets of a specific helix genes composed of a pair of blood group system Chromosomes, one from the father and one from the mother. Chromosomes in the nucleus of both parents
