Question

Quizplus · Accepted Answer

A pedigree is a chart that shows the pattern of inheritance of a particular trait or disorder within a family. It is commonly used by researchers studying single-gene inherited disorders such as Huntington's disease to track the inheritance pattern of the disease within a family. A family history or family tree may also be used interchangeably with pedigree, but the specific term "pedigree" is commonly used in genetics research. A linkage map is a different type of chart that shows the location of genes on a chromosome. Trisomy refers to a genetic condition where there are three copies of a particular chromosome instead of the normal two.
