How do you cross blood types on a punnet?
If by heterozygous you mean someone has one allele for A (AA or Aa) type blood and one for O (ii), though a third allele, for type B, is also a possibility. If the parents are AA X Ai (phenotype would be A for both) then possibilities for the offspring are: Ai and AA, and all will be type A. If it's AA (A Blood) x AB (AB blood), then their children will be either AA or AB.
If you are AB plus can your child have the same blood type as you?
The child can have the same blood type. It is possible if the child obtains the allele IA from one parent and IB from the other. So if a person with blood type AB provides IA or IB and the other parent provides the other allele, then the child may have the same blood type i.e. AB positive.
Mom o plus dad b plus baby is what blood type?
It is not possible to determine the blood type of the baby based solely on the information provided about the parents. The baby could inherit any combination of blood type alleles from the parents, resulting in a variety of potential blood types for the baby. A blood type punnett square can be used to determine the possible blood types of offspring based on the parents' blood types.
What is expressing 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
Can a parent with b blood have a child with a?
yes, a parent with a would have the genotype B,O (really IB,i) and the other parent would have A,O (really IA, i)or an alternative is A,A (really IA,IA). In atleast one of the squares in punnett squares *depending on which genotype for the second parent you chose* A,O (really IA, i) would be there.
Is it possible for a with a blood type alleles Ia and Ib to have blood type a?
In the perfect world, no. IA and IB are codominant so both alleles are represented in the person's phenotype. Blood type A can only be represented by itself in a phenotype if the person's genotype is either IA IA or IA i.(The result of a DNA mutation may be able to create a phenotype of blood type A out of a (purebred) cross (of blood type A and B).No. IA and IB are both codominant . Blood type A can only be represented by itself in a phenotype if the person's genotype is IAIA or IAi. Blood type B can only be represented by itseft in a phenotype if the person's genotype is IBIB or IBi. If the phenotype (blood type) is AB the genotype is IAIB.
IA and IB are dominant to?
IA and IB is dominant to ii or sometimes preferred IO.
Why are IA and IB alleles considered codominant?
The IA and IB alleles code for the A and B antigens on the membranes of erythrocytes. These two antigens can exist together, as in a person with the AB blood type. Since the two alleles can express their character simultaneously, they are considered codominant.
How many genes are involved i determining your blood type?
the human blood type is controlled by the gene 'I'. It is of 3 types Ia, Ib and i. the alleles 'Ia' and 'Ib' produce slightly different sugar polymers protruding on its surface while the 'i' doesn't produce any sugar polymers. as humans are haploid the contain 2 alleles out of the 3 I gene alleles, as the individual alleles come from the parent gamete. the alleles 'Ia' and 'Ib' are completely dominant over 'i', i.e, if alleles 'Ia' and 'i' are present then only the allele 'Ia' will be expressed, and the same for 'Ib' and 'i' happens, but when 'Ia' and 'Ib' are present together then they both express their own types, this is because of the co-dominance. Ia + Ia = IaIa = A Ia + Ib = IaIb = AB Ia + i = Iai = A Ib + Ia = IbIa = AB Ib + Ib = IbIb = B Ib + i = Ibi = B i + i = ii = 0 (zero commonly known as O)

If it's AA (A Blood) x AB (AB blood), then their children will be either AA or AB.
What ab blood type?
Ia Ib
What is AB blood type?
Ia Ib
What is the expected genotypic ratio among children born to a mother having the genotype IAiO and a father with the phenotype A?
The mother will produce two types of gametes: IA and IO (mother is A) The father is AB his genotype is IAIB, thus he will produce these kind of gametes: IA and IB Four combinations are possible IA from Mother and IA from Father: The child has genotype IAIA and he has blood group A IO from Mother and IA from Father: The child has genotype IAIO and he has blood group A IA from Mother and IB from Father: The child has genotype IAIB and he has blood group AB IO from Mother and IB from Father: The child has genotype IBIO and he has blood group B Thus the phnotypic ratio is blood group A:B:AB = 2:1:1
What are genotype of blood typE ABO blood system?
Ia Ib
How do alleles make it possible for humans to have four different traits for blood type?
Blood type in humans is determined by three alleles: A, B, and O. These alleles create four different blood types (A, B, AB, and O) through various combinations. A and B are co-dominant, while O is recessive. A person can inherit two different alleles (heterozygous) to have a blended blood type (AB), inherit two of the same alleles (homozygous) to have a pure blood type, or inherit the recessive O allele to have type O blood.
If you are AB plus can your child have the same blood type as you?
The child can have the same blood type. It is possible if the child obtains the allele IA from one parent and IB from the other. So if a person with blood type AB provides IA or IB and the other parent provides the other allele, then the child may have the same blood type i.e. AB positive.
What is the expected phenotypic ratio among children born to a mother having the genotype IAiO and a father with the phenotype AB?
The mother has blood type A (IA) and is a carrier of the recessive O (iO) allele. The father is blood type AB, meaning he has both A and B alleles. Their children would have a 50% chance of inheriting the A allele from the mother and a 50% chance of inheriting the B allele from the father, resulting in a phenotypic ratio of 100% AB.
