The analysis of family pedigrees provides data on inheritance patterns through several generations and is useful for preparation of linkage maps.
A pedigree chart shows genetic connections among individuals using standardized symbols. Knowledge of probability and Mendelian patterns are used to suggest the basis of a trait. Conclusions are most accurate when they are drawn from large number of pedigrees.
This animation (Audio - Important) describes pedigree charts.
