Introduction An experiment was done to determine the allele frequencies for a gene in a model population and to describe the affect of natural selection on this population. The Hardy-Weinburg theorem states that the gene pool of a non-evolving population remains constant over generation but the natural effect of Hardy-Weinburg’s equilibrium by selecting the individuals who are most fit for the environment, and allowing them to reproduce more of the genotype that is allowing them to survive. The equation for Hardy-Weinburg equilibrium uses the letter p to represent the frequency of one allele q for the other allele. The sum of both allele add up to one or one hundred percent for that population. To calculate the frequency we use

The null hypothesis for this experiment is that the flashier the male are more attractive they will become to the female and predators. This will lead to the decrease of population and changes in the population. The frequency for the color fishes will decrease as time passes.

Methods
For this particular experiment we had two different lab tests. For the first part of the experiment it was necessary to use a computer and log on the http://www.pbs.org/wgbh.evolution/educators/lessons/lesson4/act2.html and lunch the Sec and the Single Guppy web activity. Running the simulation on the web site and selecting “I’m ready to find out” will start the experiment. Choosing the causes guppy color variation will give detail information’s on the guppy environments.
For the second part of the experiment, we had hundred red and white beads. We placed the beads in a large container and mixed the beads. We than labeled (FF) (Ff) and (ff) in three different containers. (FF) represents the dominant homozygous, (Ff) is a heterozygous and (ff) that having no fur. The experiment simulation took in the absence of heat. Bunnies with the (ff) will not make it through the
