Zygosity Testing


Pricing starting at $349 CDN -- Order Now

A zygosity will determine if twins, triplets, etc. are identical or non-identical (fraternal).


What can I expect my result to say?

The results issued for a zygosity test will be either identical whereby the tested individuals have identical DNA at the tested regions or fraternal whereby the tested individuals do not have identical DNA at the tested regions.


Understanding this test

Identical twins (also called monozygotic twins) occur when a single egg is fertilized by a single sperm and the egg subsequently divides into two separate embryos. Identical twins will have identical DNA at the regions tested. Non-identical/fraternal twins (also called dizygotic twins) typically occur when two eggs are fertilized by two different sperm. Fraternal twins are as genetically similar to one another as any siblings that share both parents, but will not have identical DNA at the regions tested.
