Answer:
Hi let me put it in this way
Step-by-step explanation:
Dr. Nancy Wexler likely used family pedigree charts as a starting point for her search for the Huntington gene because they provide a visual representation of the genetic relationships within a family. By looking at the family pedigree charts of the people of Lake Maracaibo, Dr. Wexler could see how the Huntington gene was inherited within families, which would help her identify patterns and possible risk factors for developing Huntington's disease. In addition, looking at family pedigree charts could help Dr. Wexler identify families with a high incidence of Huntington's disease, which would be a useful starting point for her research. By using these charts as a starting point, Dr. Wexler could more efficiently and effectively begin her search for the Huntington gene.
