Blood Type Because they don't have an O to pass on! 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.Sep 7, 2011
They are B blood type but can pass the O onto their kids. So two B parents can make an O child if both parents are BO. ... If mom passes her O and so does dad, then the child will be OO which is O type blood. Each parent has a 50% chance of passing down the O gene.Nov 17, 2006
How are ABO alleles inherited by our children? Each biological parent donates one of their two ABO alleles to their child. 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.
But it is technically possible for two O-type parents to have a child with A or B blood, and maybe even AB (although this is even more unlikely). In fact, a child can get almost any kind of blood type if you consider the rule-breaking exceptions.Jul 14, 2006
Someone who has an A and a B version of the blood type gene makes both A and B proteins. And so is AB blood type. But someone who has a B and an O version only makes the B protein. They are B blood type but can pass the O onto their kids....Menu.GenesBlood typeBBBBOBABABOOO2 more rows•Nov 17, 2006
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, they can either produce a child with A, B or AB blood types....ABO Blood Type Calculator.Genotype (DNA)Blood TypeAO or AAA blood typeABAB blood typeBO or BBB blood typeOOO blood type
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.
Could an individual with blood type O (genotype ii) be a legitimate child of parents in which one parent had blood type A and the other parent had blood type B? Yes this child could have come from these parents.
Neither of your parents has to have the same blood type as you. For example if one of your parents was AB+ and the other was O+, they could only have A and B kids. In other words, most likely none of their kids would share either parent's blood type.Oct 15, 2015
No, siblings don't necessarily have the same blood type. It depends on the genotype of both the parents for the gene determining the blood type. E.g. Parents with the genotype AO and BO can have offspring with blood type A, B, AB or O.
type ABIn the U.S., the blood type AB, Rh negative is considered the rarest, while O positive is most common.May 18, 2020
Yes this is definitely possible. In this case, the most likely explanation is that dad is a carrier for being Rh- and mom is a carrier for blood type O. What happened was that dad and mom each passed both an O and an Rh negative to the baby. The end result is an O negative child.Jul 24, 2013
