explain co-dominance selecting the example of ABO blood group system
What else can I help you with?
What is the ABO blood system and Co-dominance?
This means if you get the "A" (or B) gene from one parent, and the "O" gene from another parent, your phenotype (in this case your actual blood group) will be A. The O gene doesn't produce a blood group at all, A and B genes do.
When both alleles are expressed in offspring is what?
Codominance is when both alleles are expressed in the offspring. This results in a phenotype where traits from both alleles are visibly present. An example of codominance is the ABO blood group system in humans.
What are the two terms best describe the inheritance of human blood types?
The two terms that best describe the inheritance of human blood types are "co-dominance" and "multiple alleles." Co-dominance refers to the expression of both alleles in a heterozygous individual, as seen in the AB blood type where both A and B antigens are present. Multiple alleles indicate that there are more than two alleles for a genetic trait, as in the ABO blood group system, which includes A, B, AB, and O types.
What blood type is an dominance?
In the ABO blood group system, blood type A is considered to be dominant over blood type O. This means that if an individual inherits one allele for type A from one parent and one allele for type O from the other, their blood type will be A. Blood type B is also dominant over type O, while blood type AB is considered co-dominant, expressing both A and B antigens.
What is expressed when both alleles for a gene are equally expressed as in human blood type?
This is called co-dominance. This is when 2 or more alleles are expressed at the same time. In other words they both affect the phenotype. In the example of human blood ABO type we have an allele for A = IA, B= Ib O=iIAIb = AB blood typeIbIb = B blood typeIai = AIaIa = A bloody typeIbi = B blood typeii = O blood type
Is blood type an example of polygenic inheritance?
It is co dominance (AB)
In humans blood type inhenitance is an examle of?
It can be an example of co-dominance, a seen in people with type AB blood.
What allele pair would show co-dominance of blood types?
Type AB
What is expressed when both alleles for a gene are equally exprssed as in human blood type?
co dominance
Is expressed when both alleles for a gene are equally expressed as in human blood type?
This is called co-dominance. This is when 2 or more alleles are expressed at the same time. In other words they both affect the phenotype. In the example of human blood ABO type we have an allele for A = IA, B= Ib O=iIAIb = AB blood typeIbIb = B blood typeIai = AIaIa = A bloody typeIbi = B blood typeii = O blood type

This is called co-dominance. This is when 2 or more alleles are expressed at the same time. In other words they both affect the phenotype. In the example of human blood ABO type we have an allele for A = IA, B= Ib O=iIAIb = AB blood typeIbIb = B blood typeIai = AIaIa = A bloody typeIbi = B blood typeii = O blood type
