我會係咩血型呢?

因為你細佬係 O 型
即係你爸爸有可能係 A, B, O 是旦一種
而你就有可能係 A, B, O 是旦一種
其中 O 型既機會比較大

Blood type O is come from 2 recessive alleles of blood type O.
Since your brother has blood of type O, he is homozygous recessive for his blood type. He must received one recessive allele from your mother and one from your father. So, your mother and father must possess at least one allele for blood type O.
Your father is either heterozygous(blood type A or B) or homozygous recessive(blood type O).
You received one recessive blood type O allele from your mother. Since your allele received from your father is not known, you may be heterozygous(blood type A or B) or homozygous recessive(blood type O), but impossible to be blood type AB.

係genetics ge 角度黎睇 blood group 係multiple alleles

係genotypes 黎睇
A 型可以係 IaIa or Ia i
B 型就係 Ib Ib or Ib i
AB 型就一定係 Ia Ib
O 型就一定係 ii

所以如果爸爸媽媽都係O型 仔女都一定會係 O型la`

唔好意思...原來講緊細佬
不過一樣
媽媽係O 型, 細佬係O 型
咁即係爸爸有可能係 A,B,O 型
咁呢...你都會有可能係A,B,O 型ga
不過就一定唔會係AB lor

因為你可能係 Ia i , Ib i, or ii 都得

最有可能係O型(由媽媽遺傳),or由你爸爸遺傳其他血型
惑者兩者一齊遺傳~我就係this
我係兩個都遺傳曬~AB型

順帶一提:AB型血的人可接受任何血液~
而AB型血只可捐給AB型血的~

你會有可能係O型或者跟你爸爸個血型。但係一定唔會AB。
