Secretory type - Bifidus type

Japanese: 分泌型 - ぶんぴつがた

Genetic polymorphisms related to human blood type substances. ABO blood type substances are not only found in red blood cells, but also in secretions such as saliva, gastric juice and semen, and the amount of ABO blood type substances is genetically determined. They are divided into secretory types (S or Se), which secrete large amounts, and non-secretory types (s or se), which secrete small amounts, with 75% of Japanese people being secretory types. It is inherited through Mendelian inheritance, with S being dominant over s, but there are also intermediate types that are difficult to distinguish because it is a quantitative trait. For secretory types, ABO blood type can be determined from saliva, semen, etc., which is important in criminal investigations. →Blood types

ヒトの血液型物質に関する遺伝的多型。ABO式血液型物質は赤血球だけでなく，唾液(だえき)，胃液，精液などの分泌液中にも含まれるが，その量は遺伝的に決定されている。分泌量の多い分泌型（SまたはSe）と，分泌の少ない非分泌型（sまたはse）に分けられ，日本人では75％が分泌型。メンデル遺伝をし，Sはsに対し優性であるが，量的形質のため判別の困難な中間型もある。分泌型では唾液，精液などからABO式血液型がわかり，犯罪捜査上重要。→血液型
