Question
1. how does a pedigree chart differ from a family history
a pedigree chart and a family history give the same information about gamily member relationships and genetics
a pedigree chart shows the genetics for a trait passed among members of a family. A family history shows the relationships between members of a family as well as the genetics.
a family history shows all the members of a family and the relationships between them. a pedigree chart is the same but adds the genetic information for a trait
a family history shows the genetic traits for each member of a family through generations. a pedigree chart shows the relationships each member of a family has to the other members
2. if two parents are homozygous (aa) for a genetically inherited recessive trait, what is the possibility they will have a child who does not have this trait in their phenotype?

1. The most accurate distinction is:
**A pedigree chart shows the genetics for a trait passed among members of a family. A family history shows the relationships between members of a family as well as the genetics.**
A pedigree chart specifically illustrates genetic traits and how they are inherited through generations, while a family history provides a broader overview of familial relationships and may include genetic information but is not focused solely on specific traits.
2. If two parents are homozygous (aa) for a genetically inherited recessive trait, what is the possibility they will have a child who does not have this trait in their phenotype?
**0%**
Since both parents are homozygous recessive (aa), all their offspring will also inherit the recessive alleles (a from each parent), resulting in 100% of their children being homozygous recessive (aa) and displaying the trait in their phenotype.
