How type A and AB parents could produce a child of blood type O?
She is A blood type but like the father, also carries an O version of the ABO gene. As you can see in the image to the right, these two parents can have an O child. In fact, every one of their children would have a 1 in 4 chance for being O. And this is just the most common way an AB parent can have an O child.
What can be the blood group of offspring when both parents have AB blood group?
“What can be the blood group of offspring when both parents have AB blood group?” When both parents have blood group AB(IAIB) then offsprings can have blood groups A(IAIA),B(IBIB)orAB(IAIB) but not O as allele i is not present in any of the parents.
Can parents with A and O blood type have AB baby?
Each person passes on only one gene for blood type and one gene for rH factor. Notice that Neither parent, in this case, has a B gene to pass on. So, no, there is no way for two parents who have A+ and O – blood, to have a child who has blood type AB +.
How is a baby’s blood type determined?
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 happens if both parents are AB?
Two parents with blood type AB will have a baby with either A, B, or AB. Two parents with the O blood type will have a baby with O. One parent with blood type A and one parent with the B blood type might have a baby in any blood group.
What blood type can two parents with A and B produce?
Two parents with A blood type can produce a child with either A or O blood types. Two parents with B blood type can produce a child with either B or O blood type. One parent with A and another with B can produce a child with A, B, AB or O blood types. If one parent has A and another has AB,…
What are the chances of my child’s blood group being AA?
Now, multiply the probabilities to obtain the chance for each blood group: 1 The chance that your child’s genotype is AA is 75\% * 50\% = 37.5\%. 2 The chance that your child’s genotype is AB is 75\% * 50\% = 37.5\%. 3 The chance that your child’s genotype is A0 is 25\% * 50\% = 12.5\%. 4 The chance that your child’s genotype is B0 is 25\% * 50\% = 12.5\%.
What are the chances of my child having an AB genotype?
Your child will either inherit an A allele (50\% chance) or B allele (50\% chance) from your partner. Now, multiply the probabilities to obtain the chance for each blood group: The chance that your child’s genotype is AA is 75\% * 50\% = 37.5\%. The chance that your child’s genotype is AB is 75\% * 50\% = 37.5\%.
How do you calculate the probability of having a different blood type?
For example, your blood group is A, and your partner’s is AB, you can calculate the probabilities for possible blood types as follows: Write down your blood type and accompanying alleles. As your blood group is A, you either have AA or A0 alleles. Your child will either inherit an A allele (75\% chance) or 0 allele (25\% chance).
