Identical Twins or Fraternal Twins?
Identical Twins
When one egg is fertilized by one sperm cell, and then divides and separates, two identical cells will result. These cells will develop into identical twins. The DNA of identical twins is exactly same. Physical attributes will also be similar.
Fraternal Twins
When two eggs are independently fertilized by two different sperm cells, fraternal twins result. The DNA profiles for fraternal twins will not be identical. However their physical attributes may be similar.
The Twin Zygosity DNA Test is used to establish DNA profiles for the twins being tested. If the profiles are different, then the twins are fraternal, and if the profiles are identical then a probability of being identical twins is calculated. Results are available in 3-5 business days after specimens have reached the laboratory.
