Question

In a real rabbit habitat new animals often come into the habitat (immigrate), and others leave the area (emigrate). How might emigration and immigration affect the gene frequency of F and f in this population of rabbits? How might you simulate this effect if you were to repeat this activity? Is this evolution, adaptation?

Answer 1

Immigration and emigration can change the gene frequency. As if the rabbit containing F genes are moving out of locality and rabbit containing f genes are immigrated continously it will lower the F gene frequency and increase f gene frequency in the rabbit population of that area. To simulate this effect the rabbit with F allele should immigrate and with f allele should emigrate so that compensate the changed allele frequencies. This is evolution and continous change in allele frequency may cause fixed one allele kn population.
