Answer:
c. The P allele is less frequent in the US than the p allele.
Explanation:
If people with the heterozygous genotype "Pp" present polydactyly, only people with the genotype "pp" will not present polydactyly. Since 99.9% of the population do not exhibit polydactyly, then it can be concluded that the "p" allele is much more frequent in the US than the "P" allele.
