What are the blood type percentages if you cross a heterozygous a mother with a heterozygous b father?
If the father is heterozygous, there is a 50\% probability for a blood type A child and a 50\% probability for a blood type O child. If the father is homozygous, every offspring will be blood type A….Rh factor.
| Mother’s Possible Rh factor | Father’s Possible Rh factor | Child’s Possible Rh factor |
|---|---|---|
| Rh+Rh- | Rh-Rh- | Rh+Rh-, Rh-Rh- |
What is heterozygous for blood type A?
When one of the inherited alleles is A and the other is B, the genotype is heterozygous and the blood type is AB. AB blood type is an example of co-dominance since both traits are expressed equally. Type A: The genotype is either AA or AO.
What is the blood type of the father if the daughter is type O and the mother is type A?
A mother who is blood type O can only pass an O allele to her son or daughter. A father who is blood type AB could pass either an A or a B allele to his son or daughter….How are ABO alleles inherited by our children?
| Inherited | Blood type of child |
|---|---|
| O from the mother B from the father | B |
What if both parents are O positive?
A child with type O blood can have parents with type A, type B, or type O blood, but not type AB. Conversely, if two parents both have type O blood, all their children will have type O blood.
How do you determine blood type from parents?
Blood Inheritance Just like eye or hair color, our blood type is inherited from our parents. 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 is the genotype of the heterozygote?
Listen to pronunciation. (HEH-teh-roh-ZY-gus JEE-noh-tipe) The presence of two different alleles at a particular gene locus. A heterozygous genotype may include one normal allele and one mutated allele or two different mutated alleles (compound heterozygote).
Is blood type A genotype or phenotype?
A phenotype consists of only those traits or antigens that can be directly typed, whereas a genotype is the sum of all genes a person has inherited within a blood group system….Table 4-5. Correlation of ABO phenotypes and genotypes.
| Phenotype | Possible Genotype |
|---|---|
| A | AA or AO |
| B | BB or BO |
| AB | AB |
| O | OO |
Do both parents have to have Type O blood?
To be O, you usually need to get an O from both mom and dad. But an AB parent usually has an A and a B version, not an O. So they usually can’t have an O child.
How can a child have blood group O if his parents have blood group A and B?
If the Mother’s blood type is B, and the father’s blood type is O, then their child must be either B or O. For instance, if both mother and alleged father have type A blood, then the child can only have A or O blood.
Is PP genotype or phenotype?
There are three available genotypes, PP (homozygous dominant ), Pp (heterozygous), and pp (homozygous recessive). All three have different genotypes but the first two have the same phenotype (purple) as distinct from the third (white).
What is the genotype of the offspring of the father?
The genotype of father is AA and of mother is OO. So by using a Punnett square, you will see that each child born will have a genotype of OA or AO. So phenotypically every offspring will have A blood group and a genotype of AO.
What is the ABO blood type of the father?
The ABO blood type of the father if the blood type of the mother and the child are known (bottom chart). ABO blood types can be complicated to understand. This is mostly due to the fact that the ‘O-type’ antigen is masked by the presence of an A- or B-type antigen.
What is the genotype of a child with AO blood type?
If the father is homogenous A, and the mother must be, and if we only consider the mendelian inheritance patterns for A, B, and O blood types… then all of their children must be AO genotype and A phenotype. All the children will have same genotype n phenotype because it have only one possibilty that is AO. All children will have a blood group..
Is O+ A homozygous or heterozygous blood type?
Answer Wiki. Since the “+” in the O+ blood type means they are Rh factor – positive, they could either have an Rh+Rh+ genotype (homozygous) or an Rh+Rh- genotype (heterozygous). You cannot tell the difference without clinical testing! Funnily enough, for it being recessive, type O is the most common blood type in North America,…
