Evolution is a change in frequencies of alleles in the gene pool of a population. This definition of evolution was developed as
a result of the work in the 20th century by Hardy and Weinberg. Through mathematical modeling based on probability, they
concluded that allele and genotype frequencies in a population will remain constant from generation to generation in the
absence of evolutionary influences. Evolution will not occur in a population if seven conditions are met:
1. mutation is not occurring
2. natural selection is not occurring
3. the population is infinitely large
4. all members of the population breed
5. mating is totally random
6. everyone produces the same number of offspring
7. there is migration in or out of the population
In northern Canada, a population of rabbits was predominantly white in color. The allele for white color is recessive (9), while the
allele for gray color is dominant (G). Over the last several decades, the average annual temperature of this area has increased, and
the long-term deposits of ice and snow have become scarce. We see the result of this change in the graph above. How would
Hardy-Weinberg explain this change in terms of allelic frequency?
