Model experiment 3. Modeling the effect of gene flow on the genetic structure of the population
 Fold the chips for both populations into separate packages. Mix the chips in each of them.
 Without looking into the first package, get 2 chips and put them in one of the three packs: the first one is a pair of red chips, the second one is a pair of red and white, the third one is a pair of white chips. Do this until you remove all the pieces from the package. Thus, the genetic structure of the population of A is modeled.
 Calculate the number of paired chips in each pile. Put results in the row for population A in table 4.
 Follow steps 2 and 3 with chips from the second pack by simulating the genetic structure of population B. Enter the results in the row for the population in table 4.
 Collect all the chips in one package, mix and repeat steps number two and three successively two more times, filling in the rows in the table for the newly formed population C and its first generation. So we simulate the process of merging populations A and B.
 Calculate the frequency of genotypes and genes in each population, fill in the table 4.
 Formulate the conclusion according to the plan:

 the ratio of frequencies of genotypes in the population;
 ratio of gene frequencies in a population;
 the direction of evolutionary change.

Note: Gene frequencies are calculated automatically by the method of extracting square roots from the frequencies of homozygotes.
