All pairs of twins are either identical (monozygotic) or fraternal (dizygotic). Contrary to what you may have thought, you usually can't tell the difference just by looking at twins, especially when they're younger. Even some traditional indicators of zygosity, like the number of placentas present at birth, are often misinterpreted or inaccurate. The only surefire way to know zygosity is by comparing the twins' DNA.
Dizygotic, or fraternal, twins occur when two distinct eggs are each fertilized by a distinct sperm. In rare cases, dizygotic twins can even have separate fathers. Monozygotic twins, on the other hand result when one sperm fertilizes one egg, and that embryo splits into two. That means that monozygotic, or identical, twins always contain exactly the same genetic material or DNA, because their DNA came from the exact same gametes.
A twin zygosity test simply analyzes the DNA of each twin and checks whether or not they are the same. A simple DNA test can show conclusively whether or not a pair of twins are identical or fraternal. That knowledge carries implications beyond the satisfying of curiosity; identical twins are genetically more compatible with each other, meaning they are excellent candidates for all kinds of organ and tissue donations.

The only way to know zygosity for sure!
Other traditional means of determining zygosity (the eye test, placenta count, etc.) are unreliable at best. At times, they're actually misleading. Until you actually get a professionally executed DNA test, you can't know for sure. There are lots of reasons for wanting to know, including important medical and legal questions, but don't overlook the value of satisfying your curiosity by finding out the truth once and for all. You could even turn the whole process into a fun family activity or science project for your kids' school.
Assess and understand your options!
When it comes to organ and tissue donation, many times the most difficult part of the process is finding a match. Family members are much more likely to qualify as donors, and the most likely to do so are identical twins. Fraternal twins only share as much DNA as typical siblings, while identical twins are for all intents and purposes genetic matches. That means an identical twin can be counted on to provide organs and tissue to his or her twin with the highest possible success rate. That information isn't always necessary, but in emergencies, it can save valuable time in moments when it's really needed.
