ow reliable is dna paternity testing? If the 1st test excluded the father will a second test include a father?

DNA tests are quite reliable. If the second guy is not the father either, than that test will also exclude him.\nI hope you are not like these mothers on Maury Povich who go through 20 guys before they find the father of their child, that is just WRONG!!!

This is called Chimera. After the mythological beast which had body parts of different sets of animals.\nA Chimera will usually have their blood and tissue of one DNA, while their reproductive organs and some inner organs will be of another. This is fairly random as to the "where" and "what," and it usually comes up as a concern in DNA testing when a mother is seemingly not the parent of her child. Or in crime cases where they cannot identify the rapist based on semen.\nThis condition occurs when two twins are begining to form within the womb, and for whatever reason one twin dies--and the other cell takes on the DNA--as a "clean up" if you will. The result is that the one cell finds no reason not to use the perfectly good DNA, and incorporates both wherever it sees fit.

no, he can't be the father of both children... the man (or male/m) with a blood type AB  has a genotype of AB while the woman with blood type B can either have a genotype of BB or BO...\n\nif a man with genotype AB is crossed with a woman (or female/f) with a genotype of BB then...\nm&#92;f B B\nA AB AB\nB BB BB\n-----------\n2 AB : 2 BB\nor 50% type AB and 50% type BB\n\nbut if a man with genotype AB is crossed with a woman (or female/f) with a genotype of BO then...\nm&#92;f B O\nA AB AO\nB BB BO\n-----------\n1 AB : 1 AO : 1 BB : 1 BO\nor 1 AB : 1 AO : 2 B_\nor 25% type AB, 25% type A and 50% type BB\n\nthus, he can be the father of the child with type A blood but he cannot be the father of the chid with type O blood.

actually, that's not 100% true.  identical twins have the same genotype at birth, so most simple paternity tests would NOT be able to tell a difference.\n\nHowever, as twins age (and we hope they have if you're sleeping with them), certain genes are activated in one and not in the other.  This means that more sophisticated genetic testing MIGHT be able to tell a difference.\n\nOtherwise, we figure you're pretty safe.  I hope it was a good threesome!

Maybe your local child protective services agency can help you. They deal with this sort of thing all the time and can tell you what you need to do. \n\nI would get notarized affadavits/statements from anyone who has information about this man. Also, you can demand a DNA test if there is some doubt about whether he is the father.\n\nGood luck. It sounds like you are the best hope for these children.

Never, just like their DNA, and the shape and structure of their eyes, their finger prints will not be the same, some time there are born identical twins to parent that look alike 99.9% but the only thing that make them different is that .1% and their DNA and finger prints, it is just a divine way of God creating his creatures,

Mother's genotype is X*X and dad's genotype is XY.\nX*X -------> 1/2 X* & 1/2 X\nXY --------> 1/2 X & 1/2 Y\n\nKids genotype will be: 1/4X*X, 1/4XX, 1/4X*Y, 1/4XY\nTherefore, there is a 25% chance of having a daughter who is a carrier, 25% chance of having a daughter who is not a carrier, 25% chance of having a hemophilic son and 25% chance of having a healthy son.

The court will mandate a paternity test, if parenthood is in question.\n\nAlso, if she is receiving any type of state aid for the child, they too, will require a paternity test.\n\nYour brother-in-law needs to get in touch with someone who can give him some good and proper advice in regards to this matter; that follow the laws of the state you live in. Have him call the friend of the court for starters.

Ok so I heard that there is slight possibility the vasectomy fails....but it's a VERY slight chance of it happening. If you feel that there is some question, get a DNA test.

A DNA maternity test involves the same as a DNA paternity test.  They verify the maternity of an individual.  It is used for various cases like for persons that are adopted and then reunited with their biological mother or they do it if they suspect some sort of mixup with babies at a hospital.  Sometimes it is used for babies that are born from in vitro fertilization to verify that the doctor implanted the right embryo.

lol . . . finally a great question . . . \n\nI read the article too . . . and it felt like it was written by a woman . . . the way she reference the Percentages as Only 10% or Only 33%.  Do you really need the word only . . . no you don't . . . it is the womens way minimizing an actually large number . . . odds are the numbers are probably higher . . . and they went with the lowest in the article. . . from a different group.  This article tries to downplay the problem of women accusing men falsely \n\nYou know . . . this is fraud on the basic level . . . and if paternity went uncontested after a certain time period then . . . and then it is discovered that the child is not his . . . even if it is genetically proven.  He is still stuck paying child support.  Fraud is a crime . . . yet the government support this felony.\n\nLook at the links . . . from my blog.\n\nhttp://blog.360.yahoo.com/blog-1fu03lEleqEHvVmUM.5t9K4-?p=31\nhttp://blog.360.yahoo.com/blog-1fu03lEleqEHvVmUM.5t9K4-?p=35\nhttp://blog.360.yahoo.com/blog-1fu03lEleqEHvVmUM.5t9K4-?p=85\n\nThis is wrong as it is selfish . . . I also answered your question regarding what is the most selfish thing a person can do . . . \n\n- - - \n\nYes . . . paternity testing is expensive . . . but is covered by most insurance . . . it is also optional in most hospitals.  But the father is afraid to ask for it . . . so not to insult his wife or girlfriend.  If it becomes manditory . . . this type of testing will radically go down in price . . . because the demand is there.  The main reason why it is a little pricy . . . is because the demand is low . . . and the training cost is high.  The demand was higher . . . then they would be more busy . . . and utilizing their training more and the cost will go down.\n\nAlso . . . the DNA testing . . . should be done by the hospital too . . . not only to confirm parentage . . . but if god forbids something happens to the child and the child needs an organ . . . 98% . . . a compatible organ can be found in the biologically father and someone answered that 1 of 6 is not compatible (in the pregnancy section) . . . and those are people who believe they are the biological fathers. \n\nThing is the parents . . . don't even need to know about the test or the results . . . unless it is proven that the father is not the father.\n\nWomen will say it will be an invasion of privacy . . . those who say that have something to hide.  It is not something to feel insulted about . . . those who feel insulted have insulted the guy they were with because they hope that the man they want is the father.\n\nPlus . . . I don't care if we put Maury out of business . . . this needs to be resolved and quickly.

Yes,there should be worried if father is Rh+ and mother is Rh-.This also may not creat problem for thier first child because mother blood has not started  making antigen against Rh+.But after thier after thier first child has been born then, of course, mother has started making antigen.Then thier second child child will die of embryonic erythroblastosis.I think you have understand the process.

hello there. I have fears just as you do. I have a now 6 year old son with epilepsy who after all these years I am being told I have to do a paternity test. The father told me if it ever came to this that he would fight me all the way and take my son who he's never been a part of his life away from me. I refused to pursue with the dna test but was told if I didn't the state would. This terrifies me so much. I absolutely know what your fears are. As for can a judge do this?. I was always told a judge couldn't try a case unless both parties have an attorney. Did you sign away your rights to an attorney? If so then the judge does have the right to make this decision especially if this is what the child wants. If your child didn't want to go then the judge should not have sent him to this abuser. I would appeal the case for the best interests of your child, especially since this guy was an abuser. Make sure when you go back to court to have an attorney, and all paperwork(police reports,etc) showing that this abuse was going on.  Let me know if I can help anymore .

The most fathererd would have to be the story not long ago about the guy who worked at the sperm bank and was making regular deposits and trading out other peoples stuff for his. Not sure on the total number's but I think it happened in the north east part of the country. I know he had so many and was found out when 2 of his kids almost got married to each other, thank god for the blood test I guess.

The birth certificate should at the very least have the mother's name on it, if not the father's, and their birthdates as well, so if those matched with yours, it would be fairly reasonable, but DNA proof would be ideal.

In a DNA sibling test, two people are tested to determine whether they share the same biological parent or parents. Full siblings are individuals who have the same biological mother and the same biological father. Half siblings share only one parent. \n\nSince siblings have the same parent(s), they have matching genes much more often than do two unrelated individuals. When matches between two potential siblings are found, calculations are made to determine the probability that a sibling relationship exists.\n\nThe DNA sibling test usually shows a number of genetic matches in true biological siblings. In such cases, the DNA sibling test may show the probability of siblingship to be greater than 99%, provided the tested alleged siblings inherited genes that are not commonly present in the population. The DNA sibling test is a useful and informative test. However, testing additional known family members (in addition to the potential siblings) greatly improves the accuracy of this DNA test.
