The five major types of pedigrees, based on genetic inheritance patterns, are Autosomal Dominant (AD), Autosomal Recessive (AR), X-linked Dominant (XD), X-linked Recessive (XR), and Y-linked, with Mitochondrial inheritance also being a DocHub category, distinguishing patterns based on chromosome location (autosomal vs. sex chromosome) and dominance. Heres a breakdown of each: Autosomal Dominant (AD): Trait appears in every generation; affected individuals have at least one affected parent; both sexes equally affected. Autosomal Recessive (AR): Trait can skip generations; unaffected parents can have affected children (carriers); both sexes equally affected. X-linked Dominant (XD): Affected fathers pass to all daughters but no sons; affected mothers pass to half of children; more females affected. X-linked Recessive (XR): More males affected; affected mothers have affected sons; unaffected mothers can have affected sons (carriers); affected daughters must have affected fathers. Y-linked: Only males are affected, and an affected father passes it to all his sons. Mitochondrial: Passed from mother to all offspring (both sexes) as mitochondria come from the egg. These patterns help geneticists determine the likelihood of inheriting a trait or disorder by analyzing family trees.
