title: On the food favoritism of twins.
abstract: In the present study, there is a continuation of the authors' earlier investigations concerning food preference/refusal patterns in a group of Hungarian adult MZ and DZ twin pairs. A "Food Like/Dislike Chart" (FLDC), adapted to local nutritional habits, was applied. In order to characterize the degree of intra-pair concordance referring to the food favoritism, the concept of the "Taste Concordance Point" (TCP) was introduced. On the basis of the comparison of the TCP values obtained for the MZ and DZ pairs the conclusion can be drawn that gustatory habits are presumably influenced also by genetic factors. The results allow the possibility of applying TCP to testing zygosity.
