WebFor example, in a species of flower, there is the dominant allele B and the recessive allele b. Homozygous dominant and heterozygous flowers are purple, but homozygous dominant are white. Alleles will count the total numbers of B and b in order to find allele frequency, but phenotypic frequency only accounts for the visible colors.
