Sloths come in two colors, gray and brown. Brown (B) is dominant to gray (b). A mom sloth with brown hair (Bb) mates with a dad sloth who has brown hair (BB). What percent of the offspring will have gray hair? (Assume 100% penetrance and complete dominance)

Assuming 100% penetrance, what is the most likely mode of inheritance shown in the pedigree below? 

The following two genotypes are crossed: Aa Bb Cc x AA bb Cc. What will be the proportion of AA Bb cc among the progeny of this cross? 

In the pedigree below, the mode of inheritance is autosomal recessive. T represents the dominant allele and t represents the recessive allele. What is/are the possible genotype(s) of individual II-6?

A DNA mutation (resulting in a loss of function) in which of the following locations would lead to the inhibition of transcription of the lac operon genes?
