In a population of native snails living in the ocean, coiling is determined by a single locus with two alleles (s, s). the right coiling phenotype has the ss or ss genotype and the left coiling phenotype carries the ss genotype. researchers spent the summer collecting a random sample from the population and found 1550 right coiling snails and 450 left coiling snails. what is the genotype frequency of the left coiling snails?
