Quizplus · Accepted Answer

Geneticists use pedigrees, which are diagrams of a family tree showing the inheritance of a specific trait or disease, along with historical records to track traits through many generations of a family. This helps them to identify patterns of inheritance and determine whether a trait or disease is passed down through generations in a dominant or recessive manner. DNA polymorphisms and mitochondrial analysis can also be used in genetic analysis, but they are not directly related to tracking traits through generations of a family. Epidemiology is the study of diseases and their distribution in populations, and is not directly related to genetic analysis. Punnett squares are used to predict the probability of certain traits in offspring of a genetic cross, but are not directly related to tracking traits through generations of a family.
