3. Setting the simulation's parameters.

graphic

Clicking on the Control Panel button opens the above window.User defined parameters are:

§ Fertility (number of children per woman).
§ Number of generations covered by the simulations (i.e. the X axis).
§ Starting roll figure.
§ Maximum roll figure.
§ Number of alleles.
§ For each allele: starting frequency in the population, lethality of the homozygous genotype .

Since the overall allele frequency is 100%, change in one frequency produces complementary changes on the others. When using four alleles reaching precisely a chosen value for all of them may need a little practice.

Any change in the number of alleles returns all frequencies to the same default value.
