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. 99 students were found to be polydactyl. The genotype of each student was also determined with the following results: 89 were genotype PP; 77 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 decitnal digits.

Inheritance and Mendelian Genetics

Inheritance means the passing of traits to offspring from parents. These traits could be passed either through asexual reproduction or sexual reproduction. The offspring receives the genetic material from the parents. Mendelian inheritance is a certain biological inheritance that follows the rules and principles laid down by Gregor Mendel in 1865. The initial hypothesis was considered wrong, but other inheritance theories modified the concept of inheritance and thus genetics.
