Twin Zygosity DNA Testing
Twin Zygosity DNA testing will determine if your twins are identical (monozygotic) or fraternal (dizygotic). homeDNAdirect provides you with a result that is 100% accurate.
Results of your twin DNA test will be ready in just 5-7 working days from receipt of samples at the laboratory.
How does a Twin test work?
Identical twins result when a single sperm cell fertilizes a single ovum and the egg then splits into 2, forming 2 separate embryos which are genetically carbon copies of each other. Non Identical twins result when two ova are fertilized independently by 2 independent sperm cells forming 2 embryos with different genetic makeups.
Our twin DNA test can confirm whether the DNA profiles of the test participants are identical (proving they are identical twins) or whether their DNA profiles are different (proving they are non-identical twins).
Our home kit will enable you to collect DNA samples using simple to use oral swabs.
You will then return the swabs for laboratory analysis.
Why do a Twin DNA Test?
- Because looking at resemblance and the physical characteristics between twins is not always a clear way of knowing if twins are monozygotic or dizygotic.
- Identical twins will have the same blood groups; they can donate blood to each other or even organs.
