Complete Home | TWIN ZYGOSITY | DNA Test Kit

Twin Zygosity DNA testing will determine if twins are identical (also known as paternal twins) or fraternal. Looking at the resemblance and the physical characteristics between twins is not always a clear way of knowing if twins are monozygotic (identical) or dizygotic (fraternal). Identical twins will have the same blood groups; they can donate blood and organs to one another. Are you looking for an at-home twin DNA test or interested in learning more about how to determine who carries the twin gene? Contact us for pricing on the zygosity DNA test.

Discreet DNA Testing Using Alternative DNA Samples

At My Forever DNA, we understand some situations require covert DNA testing. For those who want to test an individual without asking for a cheek swab, there are several alternative ways to collect a DNA sample. Discreet testing is possible using samples such as hair, toothbrushes, fingernail clippings, ear wax swabs, cigarette butts, chewing gum, and many others.

View our complete list of acceptable sources for alternative DNA samples.

When purchasing any of our DNA test kits, simply provide a cheek swab or an alternative sample for one or more of the individuals being tested. It is acceptable to send a standard cheek swab for one individual and an alternative sample for another person being tested. Hair DNA tests are common alternatives to cheek swaps.

Once the alternative DNA sample (Ex. toothbrush or hair sample) is received, it will be sent to our forensic lab for viability testing. The testing fee for viability is non-refundable.

If the sample contains enough viable DNA to process, you will be notified by email and the sample will move forward to comparison testing. Your final results will be emailed within 10-15 business days.
