1) If a child has an autosomal recessive disorder (such as albinism) and the child's parents do not exhibit the disorder, what can you conclude about the parent's genotypes?

2) If a child has an autosomal dominant disorder (such as inherited deafness), what are the child's two possible genotypes?

3) In sex-linked recessive disorders (such as color-blindness), how many copies of the recessive allele are needed for a female to exhibit the trait?

4) In sex-linked recessive disorders (such as color-blindness), how many copies of the recessive allele are needed for a male to exhibit the trait?

5) What is the one example used to understand the codominant mode of inheritance in this exercise?

-After examining the pedigree in Figure 13.2, determine the genotype for each individual on the pedigree for the ability to taste PTC. Use TT, Tt, or tt as possible genotypes.

-If there is not sufficient information to determine a person's second allele, place a question mark (?) in place of the second letter. Write the genotype below each circle or square on the pedigree chart.
