The exercise involved a series of "mating" events that resulted in 6 generations. Each mating event produced offspring with "possible" recently inherited traits. The idea of ​​"chance" was included through simple coin tosses. Furthermore, ideas of selection and mutations in the "gene pool" were introduced, which presented a deeper and clearer understanding of Mendelian inheritance and Hardy-Weinberg equilibrium. Once the third generation was reached, a B1 mutant allele was introduced into the blue fin shape influencing locus and a G1 mutant allele was introduced into the green mouth affecting locus.
