Hardy-Weinberg Principle
Genotype frequency equation
Where p² is the freq of homo dominant genotype, 2pq is the freq of heterozygous genotype and q² is the freq of homo recessive genotype.
Allele frequency equation
p + q = 1
Where p is the frequency of dominant alleles and q is the frequency of recessive alleles.
Yellow eyes in the frog offspring is a phenotype (physical trait) that would be a expressed by a geneotype (YY or Yy). This frequency, 0.85 includes: p² + 2pq
0.85 + q² = 1
q² = 0.15
p =
Then p + = 1
1 - = p
p = 0.613
