For the most likely mode of inheritance:
What is the genotype of individual 1-2? (include proper nomenclature punctuation)
What is the probability that individual III-2 is heterozygous? (enter a fraction in its
lowest form - i.e. 1/3 not 2/6)
If individuals II-5 and II-6 had a third child, what is the probability that it would be a
fuzzy-knuckled girl? (enter a fraction in its lowest term)
