DNA Paternity Testing theory explaned

DNA Tests

DNA (Deoxyribonucleic Acid) is the genetic material present in every cell of the human body. Except in the case of identical multiple births, each individual's DNA is unique. A child receives half of his or her genetic material (DNA) from the biological mother, and half from the biological father. During DNA testing, the genetic characteristics of the child are compared to those of the mother. Characteristics that cannot be found in the mother must have been inherited from the father.

DNA paternity testing is the most accurate form of paternity testing possible. If DNA patterns between the child and the alleged father do not match on two or more DNA probes, then the alleged father can be totally ruled out. If the DNA patterns between mother, child, and the alleged father match on every DNA probe, the likelihood of paternity is 99.9 percent. To conduct DNA testing, either a blood test known as Restriction Fragment Length Polymorphism (RFLP) or a procedure called a Buccal scrap is used. A swab is rubbed vigorously against the inside of the subject's cheek. This provides a DNA sample for testing. Children can be tested at any age. Paternity testing can even be done on an umbilical cord blood specimen at birth. Since DNA is the same in every cell of the human body, the accuracy of testing performed on cheek cells utilizing the Buccal Swab is the same as an actual blood sample.

That was highly informative! Thank you very much! :)

[ashkum]

major props for the positive phrasing of the dilemma. good for you.

[rosaravelo]

Thank you very much Dr Nikolay for your response I found genetics to be such an amazing subject

[KingKatura]

So how accurate is paternity tests as i can't seem to find anyone talking about it?

[jimdandy]

You mean two men who don't want to be blamed for knocking up a promiscuous woman who evidently had sex with (at least) 2 different men in a short span of time.

Thanks again Nikolay. Your videos are great!
Two question: 1) lets say you have AC_AC on one chromosome and AC_AC_AC_AC on the other.What happens if there is crossing over in the STR loci and for the offspring you get AC_AC_AC repeats? Can that happen?
2) how many STR are usually tested in a paternity test?

[elizeleroux]

with paternity testing if a man does it with swab on his own child and have it tested, the women should also have the child tested on her side, incase there was bribes and money paid for lies

[rosaravelo]

Finally somebody explain this DNA in an easy way thanks

[cwong]

So glad technology exists in the year 2022.

[xoaddearth]

in uk we dont test the mother just the child and a single prospective father at one time

[worldtraveler]

Is the Paternity DNA and Ancestry DNA testing done the same way?

[cheelodimuna]

This maza also? Does she NOT know the faza or ze child sure. Well, Faza 1 and Faza 2 are very unfortunate

[rosaravelo]

One question Dr. Nikolay how possible will be that unrelated test positive in a paternity test, considering two thinks, there is a limited amount of A-C-T-G combinations, and a large amount of humans ? It is this a real possibility, a remote one, a very rare one or merely imposible ?

I need to do a maternity or aunt test,
with DNA from Brest milk (frozen express milk) and my son's DNA.
My goal is to find out if the milk is from my son's mother or from my son’s aunt. This could be a very important information for a court custody case. Do you know if is posible to do this test?

[farangerman]

How do we select the loccus. And if we selected then also there is a chance of dna recombination which will give rise to new allele.

[varriovlogs]

I did my paternity test but the mom didnt get tested is that bad?

[tranjavanadbia]

Men are being forced to pay child support based on theory ????

This guy lost me in the first 30seconds with his moronic scenario. Total manipulation to make women look good, who simply are either lying to one or more men in poor character, or so promiscuous that she honesty doesn’t know and is guessing to avoid shame and embarrassment, while the suspicious man or men in sniffing this out, want the test in order not to be economically and emotionally raped by a less than long term female who can later weaponize the legally system against him if there is a large enough income disparity between accused dad and trash mom.Yes I said trash. For any women to think that this is okay to do to another human being is criminal. Lies to look good and get sex are like prayers of Mother Teresa compared to “ It’s your baby and pay me for the next 2 decades.” This act on violence against men goes back several millennia. So let be kind to one another and please...take the undeserving mothers of Hilter, Stalin, Mao, Hussein, Bin Laden, Ted Bundy, Jack the Ripper, every rapping, murder, serial killer...off the pedestals please. To know the tree, just taste the fruit. Some on that list had fathers around and some didn’t, but most if not all had mothers around. Put two and two together. Wanting equality of opportunity is far different than wanting to neutralize a group then take over its resources and-or position. This guys lame scenario perpetrates a socially damaging lie about the innate goodness of females. They are no better or moral than men.
