Allele frequencies fill in the blank and calculations. In a population of snails, some individuals have brown bands (dominant phenotype) and some individuals have red bands (recessive phenotype). If 50 individuals are captured and 30 have brown bands, estimate the frequency of alleles 8 and b. (Reference all your hill in the blanks in text box below). A. Individuals: BB 5 Bb bb B. Allele Counts C. Frequencies F ( B ) F ( b ) D. If allicle frequencies in the NEXT generation changed we could say the population.
