Each generation is represented by a Roman Numeral and each individual by a number. Based on the pedigree above, there are 2 generations. I-1 is the male parent and l-2 is the female parent. Generation Il are their children, with Il-1 as the eldest (daughter), Il-2 the middle child (son) and II-3 another daughter as the youngest. An arrow that points to any individual in the pedigree chart identifies the individual as a proband, an individual affected with a disorder (II-3 in the pedigree above) who is the first subject in a study (as of a genetic character in a family lineage) (Merriam-Webster.com). The proband can be specified in the problem. Answer the following using the spaces provided. 1. This pedigree tracks the inheritance of freckles, an autosomal dominant trait, for 3 generations. Determine the genotypes of all individual in the chart. 1-1 III-1 II-2 Il-1 1-2 Il-2 Il-3 Il-4 III-3 III-4 Il-5 III-5 III-6 If III-6 marries someone without freckles, is it possible for them to have a non-freckled child? Why or why not?
