Question
What do we use pedigrees for?
- To look at families
- To make determinations about the offspring
- To track traits in families
- Nothing
Hint:
Pedigree chart is used for phenotypic studies.
The correct answer is: To track traits in families
Pedigree chart or family tree is used to analyze the transfer of traits between generations.
Pedigree chart is represented in the form of boxes and circles, denoting males nd females, respectively. In a pedigree chart:
- Empty boxes and circles represent normal or healthy individuals
- Partially shaded boxes and circles represent carriers
- Completely shaded boxes and circles represent affected individual
The pedigree chart helps to analyze the occurrence of genetic disorder in a family.
- Pedigree chart helps to analyze the traits of individuals in a family
- The pedigree chart helps to determine the occurrence of genetic disorder that runs in a family
- Pedigree chart is represented in the form of boxes and circles (males and females, respectively)
- Normal, carrier and affected individuals can be distinguished in a pedigree chart
