Hint: Scientists use pedigree analysis in order to study the inheritance of genes in humans. A series of symbols are used to represent different aspects of a pedigree.
Complete Answer:
- Pedigree analysis is a graphical representation which shows the pattern of inheritance in a family.
- These are the charts that show the phenotype or genotypes for a particular organism and its ancestor from one generation to the next generation.
Need of pedigree analysis in human genetics:
- Pedigree analysis is used to study the inheritance of genes in humans from one generation to next generation.
- The study of pedigree is also important in predicting genetic risks.
- It is also used for predicting many genetically inherited disorders such as cystic fibrosis, sickle cell anemia, etc.
- It is also useful to find recessive and dominant types of traits.
Conclusions that can be drawn from a pedigree analysis:
- Pedigree analysis can trace the Mendelian disorders.
- It can conclude the pattern of inheritance. Pedigree analaysis tells us whether the trait is linked to the sex chromosomes or autosomes.
