The correct option is C
Either A or B
If the father’s blood group is O, he has the genotype IOIO or (ii). The mother has blood type AB, which means that her genotype would be IAIB. The possible combinations of these two groups would result in children having genotypes IAIO orIBIO, which would give them blood groups A or B respectively. Thus, blood group O cannot appear among children if one of the parents has the group AB.
There are four main blood types: A, AB, B and O. AB positive is considered the universal recipient, and O negative is considered the universal donor.
Blood type frequency (U.S. population)
- O Positive blood—37%
- O Negative blood—7%
- A Positive blood—36%
- A Negative blood—6%
- B Positive blood—8%
- B Negative blood—2%
- AB Positive blood—3%
- AB Negative blood—1%
Your ABO blood type is based on the presence or absence of the A and B antigens on your red blood cells. The A blood type has only the A antigen and the B blood type has only the B antigen. The AB blood type has both A and B antigens, and the O blood type has neither A nor B antigen.
By the time you are 6 months old, you naturally develop antibodies against the antigens your red blood cells lack. For instance, a person with A blood type will have anti-B antibodies, and a person with B blood type will have anti-A antibodies. If you have type A blood, you cannot receive B blood because your body's anti-B antibodies will fight the B blood's B antigens. It is crucial we have all blood types available to our patients.

Blood Type Comparison - CHILD, FATHER, MOTHER
Paternity Determination by Blood Type Chart Calculator
Blood type can be used to disprove paternity only in some cases.
In other words, the non-father's blood type may be the same or be of a type where either man could be the father based solely on the blood type but not in the results of a DNA Paternity test.
In paternity civil lawsuit against the mother by fathers and children
See more about the civil lawsuits brought against mothers by their husband, or males falsely reported as the father or even children in paternity fraud cases of 10 different counties on this website.
In such cases, the paternity fraud deprives a child of the relationship and heritage of the biological father and the child rights found in UN Convention on the Rights of the Child which states that a child has the right to be raised by both biological parents.

The ABO blood type charts below can be used to predict the possibilities of paternity.
The charts below can assist you to determine either:
1. The ABO blood type of the child when the blood type of the father and the mother are known (top chart), or
2. The ABO blood type of the father if the blood type of the child and the mother are known (bottom chart).
ABO Blood Type Calculator
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. This is explained in the following chart, showing the different the genotypes that make up the blood types.
| AO or AA | A blood type |
| AB | AB blood type |
| BO or BB | B blood type |
| OO | O blood type |
For example, two O blood type parents can produce a child with only O blood type. 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, they can either produce a child with A, B or AB blood types. If one parent has A and another has O, they can either produce a child with A or O blood types.
Rh Positive (Rh+) and Negative (Rh-) Blood Types
The Rh (+/-) factor is inherited separately from the ABO blood types. Similarly to the masking effect of the O gene in ABO blood types, the Rh negative (Rh-) gene is also masked by the presence of a Rh positive (Rh+) genotype. Therefore, a person may have a Rh + blood type and can still have an Rh - gene (See the chart below). Further more, 2 parents with Rh + blood types can have a child with Rh - blood type.
| (+ , -) or (+ , +) | Rh + |
| (- , -) | Rh - |

Mommy's little secret - 1 out of 6 Canadians are Victims of Paternity Fraud

Includes interview with employees of Hospital for Sick Children in Toronto, Ontario, Canada who admit they deny children's identity information to husbands/male partners of mothers who want to hide the real identity of their child because they had an affair. The U.N. Convention on the Rights of The Child specifically supports a child's human right to have a relationship with both his/her biological parents. In addition, this article is proof that The Hospital for Sick Children ("Sick Kids") supports paternity fraud.
Further "Sick Kids" supports a mother's rights only, which they view, supersedes 3 other people's rights, namely, the rights of the biological father, the rights of the mother's male partner/husband and the child's identity rights. Read More ..

An adulterous Spanish woman who conceived three children with her lover has been ordered to pay £177,000 in 'moral damages' to her husband.
The cuckolded man had believed that the three children were his until a DNA test eventually proved they were fathered by another man.
The husband, who along with the other man cannot be named for legal reasons to protect the children's identities, suspected his second wife may have been unfaithful in 2001.

A Woman's Right to be Criminal
December 5, 2002
I read a USA Today article on child support by Martin Kasindorf entitled, Men wage battle on 'paternity fraud'. Paternity fraud is when a woman names the wrong man as a father for the purpose of forcing him to pay child support. The words 'paternity fraud' were in quotes as if they referred to someone's questionable characterization rather than a straightforward fact. This might have moved me to let out a long sigh except that I knew it would not have been worth the trouble. I know from experience that 'paternity fraud' would not have been in quotes unless we were being prepared for some unadulterated bullshit. Read More ..

BEAUTIFUL women who have affairs can now blame it on their sex hormones.
Women with higher levels of oestradiol, a form of oestrogen, not only look and feel Read More ..tractive, they are also more likely to cheat on their partners, a new study has found.
One-night-stands are not what interest these flirtatious females, who tend to have bigger breasts, relatively small waists and symmetrical faces as a result of their high levels of oestradiol.
Rather, they adopt a strategy of serial monogamy, say the researchers, led by Kristina Durante of the University of Texas. Read More ..
