Fraternal Twins
Fraternal twins happen when two eggs are fertilised by two individual
sperms. Fraternal twins can be of either sex,
and usually have about 80% DNA in common.
Using the power of DNA testing
it is unambiguously possible to discriminate between identical and
fraternal twins. At DNA Bioscience, we can determine between identical
or fraternal twins by using a specially designed DNA test.
If you would like to test if your twins are identical or fraternal, please navigate to Twin Zygosity Testing.
