hello students the question says that a woman with blood group A B marriage to a man with blood group B whose mother had blood group O calculate the probability of getting their first son with blood group ab and the options are one by two 1 by 8 1 by 4 or 1 by 60 so first of all the ab blood group system in humans we know that this genetic Inheritance of abo blood group system it is influenced by multiple allelism along with codominance write these are the two factors which influence the blood group system in humans now this female order women in the question is ab right so the genotype of the female would be fi Show why I be because this gene for blood group is gene I and it is located on the chromosome 9 right Saudi women genotype would be a I know if we talk about the mail the question specifies that the man has blood group B whose mother had blood group O that means the mother of this man had blood group O and this man is having blood group B therefore this man zero type would be heterozygous because one of the chromosome it is coming from the mother that would be denoted by small and the blood group B that is decided by the gene that came from the father and his father must be blood group B so this mein would be heterozygous for B blood group now we need to find out the probability of the child with blood group ab when this woman gets married to this man right so let's see now the blood group of their progeny would be a b for this would be the phenotype but if we see the genotype when will do a cross between these two the genotypes that we will get would be for a be it would be a IB and for be it could be either homozygous been or it could be either heterozygous been and for a it would be heterozygous right these would be the genotypes of their progeny right and the probability of a b blood group is 25% out of these four types of genotype the ab blood group comprises 25% that means for ab the probability would be one fourth so our answer would be option C What are the parents with blood group O and AB?Believe it or not, in this case having a blood type different from either parent is by far the most common result. In most cases, an O parent and an AB parent will have only A or B kids.
What will be the parents blood group if the blood group of a child is ab Mcq?Complete answer:
If a child is having blood group AB (iA iB), then the parent's blood will be A (iA iA) and AB (iA iB) out of the given options. This is because the rest options are having blood group O (iO iO) which is incorrect as a child is not having an i0 gene. Hence, the correct answer is D.
Which blood group is found in offspring in a marriage between blood group?Final answer: A, B, AB, and O are the possible blood groups of offspring when a man with blood group 'A' marries a woman with blood group 'B'.
Can a man with O+ marry a woman with O+?If both are O positive then there is no risk.
Now regarding the girl known to you, if she is a close relative (second or third-degree relative) then the marriage can create a reduced genetic pool. Hence, future kid may have genetic defects or you might not have kids at all due to reduced genetic pool.
