The following template shows a pedigree chart of the five generations of the family. In the below pedigree chart, there are 24 normal family members (both male and female) and 16 members that are polydactyl. It should be noted here that a pedigree chart is a diagram that shows the occurrence and appearance or phenotypes of a particular gene or organism and its ancestors from one generation to the next, most commonly humans, show dogs, and racehorses. Instead of using complex and highly paid tools, use free pedigree chart makers like EdrawMax or EdrawMax Online that allow 100% customization as per the requirement.
