A pedigree chart is a diagrammatic representation showing the occurrence and appearance of phenotypes of a particular gene/traits and its ancestors from one generation to the next establishing relationships between individuals in a family.
Using the letter A for a dominant allele and a for a recessive allele, the genotype of individual I-1 is Aa.
- In the key pedigree nomenclature, an individual marked with the black ink is affected with the trait (and this trait is dominant - A).
- Looking at the F1 generation, there are males affected and females as well.
- For inheritance of the trait, just one copy is enough to become affected.
- Therefore, the male parent is heterozygous for the trait and the female normal (aa) to enable the production of both affected and non-affected individuals.
