Final answer:
The Amoeba Sisters use earlobe type in a pedigree to analyze genetic disorders, utilizing pedigree charts to trace inheritance patterns that can indicate how certain traits and potential genetic disorders are passed down through generations.
Step-by-step explanation:
The Amoeba Sisters use earlobe type in a pedigree to analyze genetic disorders. A pedigree chart, such as the one depicting earlobe trait inheritance, is a visual tool for studying inheritance patterns and can reveal how an autosomal dominant or recessive trait is passed through generations. This information is used in the study of genetic disorders, including those that follow Mendelian inheritance patterns like albinism, cystic fibrosis, and Huntington's disease. Moreover, genomics, which can be realized through techniques like FISH (Fluorescence In Situ Hybridization) and DNA analysis, expands upon this basic genetic understanding by determining the risks of genetic diseases for an individual's prospective offspring and possible treatment strategies.
