The population of panthers consists of 60 black panthers with the dominanat allele PP. 30 are pink panthers with the genotype Pp and 10 panthers are white with the phenotype pp.
The frequency of p allele in the population can be determined by
the number of individual with pp genotype + 1/2the number of individual with Pp genotype divided by the total number of individual.
Frequency = 10+1/2*30/100
Frequency = 0.25.
Thus, the frequency of p genotype is 0.25.
