Procedure 8.5 PEDIGREE CHARTS Pedigree charts are diagrams that illustrate how a trait is inherited through generations of a family. They can help us determine genotypes and patterns of inheritance for a trait. HOW TO READ A PEDIGREE CHART 1. Look at the sample pedigree chart in Figure 8.7. 2. Square boxes represent males and circles represent females. 3. A filled-in figure means that the trait is present in that individual. An empty figure means the trait is not present....

1. Examine each pedigree shown (a-c). The shaded square/circle shows an inherited phenotype. For each (a, b, c), write a sentence or two that indicates whether it is (or is not) consistent with X-linked recessive inheritance. If you decide the pedigree IS consistent, for full credit you must prove this by setting up a Punnett square or a forked line diagram. (6 pts) TO GO 2.

1. (2 pts) Attached ear lobes (f) are inherited as an autosomal recessive trait. The dominant allele, F, produces free hanging ear lobes. Sam and Beth both have free earlobes, but their first child has attached earlobes. a. What are the likely genotypes of Sam and Beth with respect to the ear lobe locus? Sam: F Beth: FF b. With respect to the earlobe locus, Sam's genotype is homozygous,/(heterozygous or hemizygous? (Circle the correct answer). c. If Sam and Beth...

Inheritance pattern in BRCA 1 Describe the inheritance pattern of BRCA 1 Is it recessive or dominant? Autosomal or sex- linked? Be sure to describe the genotypes and phenotypes of both the affected individuals and their parents. Are there any non-Mendelian inheritance patterns involved (e.g., co-dominance or incomplete dominance)? what does this inheritance pattern mean for individuals who have the mutated gene? use at least one diagram and text to convey this information. A pedigree chart is often a useful...
