One format that is often used in a pedigree is a chart showing the older generation at the top and the younger generations at the bottom. Descendant chart that displays all the descendants of one individual has the narrowest part at the top.
Ancestral chart, which is a tree showing the ancestors of an individual, has a shape that is more like a tree, with the top wider than the bottom. Some ancestor chart displayed by an individual is on the left and on the right ancestors.
