🧬 血型遗传计算器（ABO 与 Rh）Blood Type Calculator (ABO and Rh Inheritance)
由父母双方的 ABO 血型和 Rh 血型推算孩子可能和不可能的血型；如果知道父母的基因型（如 AO、BB），还会给出每种血型的概率。Work out which ABO and Rh blood types a child can and cannot have from both parents' types — and, if you know the parents' genotypes (such as AO or BB), the chance of each type.

如何使用「血型遗传计算器（ABO 与 Rh）」？How do I use the Blood Type Calculator (ABO and Rh Inheritance) tool?
在「血型遗传计算器（ABO 与 Rh）」中，填写「父/母 1 的 ABO 血型」、「父/母 1 基因型（可选）」、「父/母 1 Rh」、「父/母 2 的 ABO 血型」、「父/母 2 基因型（可选）」等参数，结果会随输入实时计算并显示在下方。In the Blood Type Calculator (ABO and Rh Inheritance): Fill in "Parent 1 ABO type", "Parent 1 genotype (optional)", "Parent 1 Rh", "Parent 2 ABO type", "Parent 2 genotype (optional)"; results are recalculated instantly as you type.
血型是怎么遗传的？How is blood type inherited?
ABO 血型由一对等位基因决定：A 和 B 都是显性，O 是隐性。A 型的人可能是 AA 或 AO，B 型可能是 BB 或 BO，AB 型是 AB，O 型是 OO。孩子从父母各得一个基因。Rh 阳性对阴性为显性，所以两个 Rh 阴性的父母只会生出 Rh 阴性的孩子。ABO type comes from one gene with A and B dominant and O recessive: type A people are AA or AO, type B are BB or BO, AB is AB and O is OO. A child gets one copy from each parent. Rh positive is dominant over negative, so two Rh-negative parents have Rh-negative children.
能用血型判断亲子关系吗？Can blood type prove parentage?
不能。血型只能排除一部分组合，而且存在孟买型、顺式 AB 等罕见例外。需要确认亲子关系时应做 DNA 检测。No. It can only rule out some combinations, and rare exceptions such as the Bombay phenotype and cis-AB exist. Use a DNA test if parentage needs to be confirmed.
结果可以代替医生的建议吗？Can this replace medical advice?
不能。「血型遗传计算器（ABO 与 Rh）」基于常用公式给出估算，个体差异较大，如有健康问题请咨询医生或专业人士。No. The Blood Type Calculator (ABO and Rh Inheritance) gives estimates from common formulas; individuals differ, so consult a doctor or professional for health decisions.
