How to Use the Multiple Alleles / Blood Type Punnett Square Simulator 1. Enter Parent Genotypes Look for the two boxes at the top of the page. In the first box labeled "Parent 1 Genotype," type one of the following codes: IAIA, IAi, IBIB, IBi, IAIB, or ii. In the second box labeled "Parent 2

2024年11月15日 · When considering inheritance, each parent contributes one allele to the offspring. The possible combinations of alleles can be illustrated using a Punnett square. For example, if a parent with blood type A (IAi I A i) has offspring with a parent with blood type B (IBi I B i), the potential genotypes of their children would be: Punnett Square ...

2012年3月13日 · （1）IAi； IBi分别是A型和B型血，说明I与i同时存在时显示的是I的基因所以i是隐性基因。 即IA对i是显性，IB对i也是显性。 （2）AB型血的基因型是IAIB，子女可能从父母的IA，IB的两个基因中各得到一个组合成自己的基因，组合的方式有三种IAIA或者IBIB或者IAIB血型 ...

ibib x iai: In this cross, one parent has type B blood (IBIB) and the other has type A blood (IAi). All offspring will have genotype iBi (type AB) since each parent contributes one dominant allele. So, none of the offspring will have type O blood. Based on these crosses, only the first one (iai x ii) could produce a child with type O (ii) blood.

IAi. In humans, there are two dominant blood types: A and B. The recessive blood type is Type O, shown as ii. Complete a cross between two heterozygous A and B blood type? They ask us IAi x IBi. Instead of making a Punnett square, we can just mix each allele from one parent with each allele from the other parent: IAIB, IAi, IBi, ii.

人类abo血型的决定方式iaia、iai―→a型血;ibib、ibi―→b型血;iaib―→ab型血(共显性);ii―→o型血。前后代遗传的推断及概率运算比正常情况要复杂。变式3 假设某植物种群非常大,可以随机交配,没有迁入和迁出,没有突变。抗病遗传因子r对感病遗传因子r为完全显性。

17.人类abo血型由ia、ib、i三个复等位基因控制，iaia和iai为a型血、ibib和ibi为b型血、iaib为ab型血、ii为o型血。当ib基因突变为ib(a)时，ib(a)ib(a)和ib(a)i为ab型血。下图家系中Ⅰ-1和Ⅰ-2血型均为ab型，其儿了Ⅱ-1血型为o型，经分了检测Ⅰ-1和Ⅰ-2均存在ib(a)基因。

对于复等位基因的计算,也可用遗传平衡定律来计算: iaia= (ia)2、 iai=2>ia>i、 ibib=(ib)2、 IBi =2>IB>i、 ii =i2。 例、ABO血型系统由3个等位基因IA、IB、和i来决定,通过调查一个由400个个体组成的某群体,

人的血型，常可分为a型、b型、ab型和o型．iaia和iai表现为a型；ibib和ibi表现为b型；iaib表现为ab型；ii表现为o型．在遗传时，父母分别将他们所携带的一对基因中的一个遗传给子女，而且是等可能的．例如，下表为a型（iai）父亲和b型（ibi）母亲生下的子女血型 ...
