Had Othello been able to do an infidelity test he might have avoided strangling Desdemona and save her from dying guiltless death. But infidelity DNA testing was not around in Shakespeare’s times. Today, DNA tests can tell you a lot about any suspicious stains you find on an item of clothing or on bed linen. These tests can even tell you the sex of the donor of the sample and perhaps even who the sample belongs to.
Is it a male or a female?
So you have found a stain on a jacket or on the car seat. You might want to first determine whether this stain belongs to a male or female. The amelogenin sex gene is one of the main sex determining genes in our body. It is found on both the X and the Y chromosome but displays a smaller peak on the Y chromosome when analyzed using the standard laboratory procedure for DNA analysis known as PCR- polymerase chain reaction.
Anyway, scientists can easily determine whether the DNA in the stain is male or female or a mix of both. Furthermore, they might even surprise you- we have had cases where the 2 DNA profiles belonged to people of the same sex (suggesting, for example, that the husband had been cheating with another man)
Do you suspect who your other half is cheating with?
If you have a suspicion of who your other half might be cheating with, you can send a comparison sample for testing. Let’s explain a bit further:
- The laboratory has already found a male and female DNA profile in the stain you sent in
- You have a suspicion of who the female profile might belong to
- By sending in a DNA sample of that person, laboratories can compare the two female profiles and determine whether they belong to the same female or not
- You can also sensibly ensure that you are not the donor of that DNA profile by sending a sample of your own DNA to exclude you as the donor.
It is important to realize that whilst companies offer DNA infidelity tests, you are free to draw your conclusions from the results of the test. The results will not state that there has been infidelity as this is beyond the scope of science.
