The inheritance pattern of a gene over generations among humans is studied by the pedigree analysis. Character studied in the pedigree analysis is equivalent to:
A. quantitative trait

B. Mendelian trait

C. polygenic trait

D. maternal trait

Answer :

Character studied in the pedigree analysis is equivalent to Mendelian trait.


After the rediscovery of Mendel’s work the practice of analysing inheritance pattern of traits in human beings began. Study of the family history about the inheritance of a particular trait in several generations of a family is called the pedigree analysis.


When we need to analyze an existing population we do not have the opportunity to perform controlled crosses. There comes the importance of pedigree analysis. Like how Mendelian traits expressed the inheritance of genes in the coming generations through crosses; the pedigree analysis provides details of inheritance of a specific trait, abnormality or disease in a family tree over generations.
