If you haven't already done so, Please fill out this anonymous survey which asks your opinion of the Bio 121 Prelabs.

Natural selection is the non-random, differential survival (mortality) and reproduction of individuals (genotypes) carrying alternative, inherited traits, which results in a change of the relative frequency of genotypes due to differences in the ability of their phenotypes to obtain representation in the next generation. In this Prelab, we investigate the differential survival and subsequent changes in allele frequency of two types of frogs found in the "BIO 121 pond". The two genetic types of our "Pond Frog (frogus pondii)" species are Yellow and Green. The Yellow are easier to see, therefore easier to catch (you are the predator).

For this prelab, catch as many frogs as you can (by clicking on them) and then analyze the effect of differential selection on the changes in allele frequency/time of the BIO 121 Pond Frog population.
