Can one ascertain paternity if identical twin brothers had intercourse with the same woman & impregnated her?

Question

I thought identical twins have identical DNA.

Answer 1

Identical twins do have the same DNA, so your answer would be no.

Answer 2

Good question....I'm fairly sure that you could not ascertain paternity from a DNA test. If you know what days the men had sex with her you might be able to figure it out that way. If it was on the same day or within a few days I'm not sure.

Yeah identical twins have identical DNA. There may be some epigenetic differences but i'm not sure a DNA test can pick those up.

Answer 3

no two people on earth have the same DNA. a minimum of 1 nucleoside would still differ. That's why even identical twins have different finger prints, moles and marks at different places in the body. The method of determination for paternity is through DNA fingerprinting. The DNA of the foetus and the probable fathers is isolated from skin, hair or blood samples. Then multiplied through polymerase chain reaction to get better results. Finally run on a gel electrophoresis unit. When the gel is stained and developed after completion of the reaction, distinct bands appear on the gel, much like a chromatogram. These bands are matched. Since bands are unique to each individual, those that match at least 50% with that of the child, is deemed as the male parent.

Answer 4

Asking a 2d time? boy you may have a lot of things to spare! Paternity of FRATERNAL twins... definite, they are going to through fact fraternal twins come from 2 separate egg and a pair of separate sperm, which occurs to start on the comparable time, in the comparable being pregnant. They, consequently, have relatively distinctive DNA and are guy or woman toddlers who're basically born on the comparable time. Now, if comparable twins have been to try this, that's attainable that paternity may be puzzled, as comparable twins are 2 toddlers which enhance from basically one fertilized egg. They, consequently, have comparable DNA. As a mom of twins, I honestly have many an argument with human beings who seem to have confidence that comparable twins would be distinctive genders. NO it extremely isn't the case, as comparable twins are constantly the comparable intercourse, as they convey comparable DNA. this is in basic terms Fraternal twins which would be distinctive gender or the comparable.

Answer 5

no they can't. like you stated, the DNA is almost a perfect match with identical twins and the difference is not noticable. There for the results are usually something like 99.998 for one twin and 99.996 for the other twin. And obviously the results are too close to choose one for sure.

Answer 6

Raindrops is perfectly right. We preform DNA fingerprinting in my lab.
