Study Notes
Geneticists' Tools
- Geneticists collect information to help couples and families.
- One tool used is a pedigree, a flowchart that shows the inheritance pattern of traits in a family over many generations.
Pedigree Analysis
- Pedigrees can be used to trace traits such as curly hair, straight hair, and freckles over generations in a family.
- They can also be used to examine certain disorders that can occur over generations.
Inheritance of Disorders
- Unaffected parents can have an affected child if both parents are carriers (heterozygous) of a recessive allele.
- Carriers do not express the recessive allele, so they are not affected.
