»  My twins don't look identical. Should I still spend the money for a DNA test?  (Back)

As you know, twins are either monozygotic or dizygotic. Your twins might look different to you since you notice small differences in physical and behavioral characteristics. These are phenotypes, or manifestations of their genotype. Please refer to our section on this website titled Genotype vs. Phenotype for a more complete explanation.

If this did not answer your question, please use our web questionnaire.
