Problem:
Polydactyly (the presence of extra fingers and/or toes) is due to the presence of a dominant allele "P". The students in Tucker dorm at NC State were surveyed for polydactyly. 117 students were found to be polydactyl. The genotype of each student was also determined with the following results: 87 were genotype PP; 84 were genotype Pp; and 55 were genotype pp.
Calculate the percent penetrance for polydactyly in this population of students.
Round your answer properly to 3 decimal digits.
Please show all the calculation and your work.
