Assume that a population consists mainly of individuals that are heterozygous (Tt). Homozygous recessives (tt) should then be the rarest members of their offspring and the overall population. Their phenotype will not resemble heterozygotes (Tt) or homozygous dominants (TT). Therefore, the phenotypes of homozygous recessives (tt) and their rare frequency in the population should be readily apparent to any observer. Explain how f(t) can be calculated solely from the f(tt) phenotypes seen within a population
