Fraternal twin is a kind of twins that comes from two ova, which each of them will be fertilized by the sperm. While, identical twin comes from an ovum, which fertilized by a sperm. This research is conducted in order to observe the inheritance pattern from the pedigree chart, and to observe similarity and dissimilarity phenotype between twin couple on families observed. Methods used for this research are data collection to construct pedigree, phenotype analysis to compare the similarity and dissimilarity phenotype between the twins that are observed, paraffin method to observe the form of hair from cross section and agglutination reaction to observe the blood group from the twins.
