What blood type has the alleles II?

What blood type has the alleles II?

ii – This genotype produces no protein (type O). So, your blood type does not necessarily tell you exactly which alleles you have. For example, a person with blood type A could have either two iA alleles or one iA allele and one i allele.

What alleles make type A blood?

Each biological parent donates one of two ABO genes to their child. The A and B genes are dominant and the O gene is recessive. For example, if an O gene is paired with an A gene, the blood type will be A.

What kind of blood is a combination of two alleles?

Type A blood is a combination of either two A alleles (IAIA) or one A allele and one O allele (IAi). Similarly, type B blood is coded for by either two B alleles (IBIB) or one B allele and one O allele (IBi). Type O blood can only be obtained with two recessive O alleles (ii).

Which is the best example of multiple alleles?

An individual with this type of inheritance connected to its multiple alleles will show a blended phenotype that mixes both of the alleles’ traits together. Examples of Multiple Alleles The human ABO blood type is a good example of multiple alleles. Humans can have red blood cellsthat are of type A (IA), type B (IB), or type O (i).

How are the A and B alleles expressed?

The A allele and the B allele are equal in their dominance and will be expressed equally if they are paired together into the genotype I A I B. Neither the A allele or the B allele is dominant over each other, so each type is expressed equally in the phenotype giving the human an AB blood type. Scoville, Heather.

Which is an example of co-dominance in blood?

Type AB blood is an example of co-dominance. The A allele and the B allele are equal in their dominance and will be expressed equally if they are paired together into the genotype I A I B. Neither the A allele or the B allele is dominant over each other, so each type is expressed equally in the phenotype giving the human an AB blood type.
