Why are pedigrees used to examine the genetics in human families?
Pedigrees are family trees which show the parents and offspring across generations, as well as who possessed particular traits.

Pedigrees of individual families are used by genetic counselors, to aid them in providing information to families who may be at risk for various genetic conditions.Click to see full answer. Also question is, what can genetic and pedigree analysis tell us?By analyzing a pedigree, we can determine genotypes, identify phenotypes, and predict how a trait will be passed on in the future. The information from a pedigree makes it possible to determine how certain alleles are inherited: whether they are dominant, recessive, autosomal, or sex-linked.Beside above, how would you describe a pedigree? A pedigree chart displays a family tree, and shows the members of the family who are affected by a genetic trait. This chart shows four generations of a family with four individuals who are affected by a form of colorblindness. Circles represent females and squares represent males. Also know, what is a genetic pedigree? A pedigree is a genetic representation of a family tree that diagrams the inheritance of a trait or disease though several generations. The pedigree shows the relationships between family members and indicates which individuals express or silently carry the trait in question.What types of information does a pedigree give us?Pedigree is the recorded lineage of a family. A pedigree chart is actually a diagram showing an appearance and occurrence of phenotypes in several generations. It is used to find a probability of a child inheriting a particular trait or to discover is the trait autosomal or sex-related.
