Hardy weinberg lab report

We placed them into a bowl and randomly picked two at a time to simulate breeding. Methods To show Hardy weinberg lab report genes being passed down generation to generation, we used beads to represent the bunnies and the offspring.

To do so, it necessary to distinguish between homozygotes and heterozygotes, either phenotypically or at the molecular level.

Is this a reasonable assumption for the trait of blood types? The survivability of recessive alleles was examined by selecting red and white beads from a bowl to symbolize recessive and dominant alleles - the recessive being white and the dominant being red.

Methods We began our experiment by establishing the organism and the traits we were identifying. In our data you can see that after each generation we put how many heterozygous dominant FFhomozygous dominant Ffand homozygous recessive individuals ff were made.

Our second experiment was to determine just how much the death of the recessive individuals had an effect on the gene pool. The main objective of this lab was to see the process of natural selection taking its course in nature, specifically in hairless rabbits.

We recorded the information into a chart that depicted how many individuals there were for each heterozygous or homozygous pair. Evolution in a population is often defined as a change in allele frequency over time.

In this experiment, for the PTC tester for the class the result for X2 is Any changes in the gene frequencies in the population over time can be detected. Because we were not given infinite amount of time, there were still some ff alleled rabbits that survied: The Hardy-Weinberg equilibrium, therefore, can be used to test whether evolution is occurring in populations.

They would have many disadvantages. This makes sense, but we did not predict it in our hypothesis, because it was not an outcome we took into account. This lab gave us the opportunity to observe how a specific recessive allele pairs become less likely to appear in an environment that does not suit them.

IN the first experiment we saw the recessive genotype decrease and ultimately die out. We believed this to be true, because - given time - every combination possible will take place, and all of the white rabbits would end up dying.

In the case of the hairless rabbits, they would die off in the colder months, and the haired rabbits would survive to pass on their genes. They make a good example, because they die off more quickly due to the harsh winters of England.

Without the disappearing of recessive alleles, it would be very difficult to survive for the organism carrying them.

Its name derives from Godfrey Hardy, an English mathematician, and Wilhelm Weinberg, a German physician, who independently formulated it in the early twentieth century.

Although some of the hairless rabbits survived through the generations, eventually all the furless rabbits did not survive anymore. We did this until there were no more beads in the bowl and recorded our results on a table that had 3 columns for each outcome.

We were once again getting rid of the recessive individuals after each trial. Therefore, we can use a chi-square test to determine whether a population exhibits Hardy Weinberg equilibrium for a particular gene.

Lastly, we can calculate the frequencies of the IA IB and i alleles, given a population sample in which the frequencies of individuals having blood types A, B, AB and O are known.

As shown in the graph, however, there is a clear positive curve for the FF alleled rabbits. We also conducted a second experiment that we created.

These data suggest that beaver food choice concurs with the optimal foraging theory. We had a total of ten trials signifying each new generation of alleles being paired to create one bunny.

The dominant allele was represented using F while the recessive allele was represented by f.Essays - largest database of quality sample essays and research papers on Hardy Weinberg Lab Report.

We were able to observe and record survival of the fittest in the lab as the bunnies with the recessive genes couldn’t withstand the environment while the bunnies with two dominant genes or a dominant and recessive.

In this lab we will be modeling Hardy Weinberg’s law of genetic equilibrium.

This law proposes that the frequency of alleles and genotypes in a population will remain constant from generation to generation if the population is stable and in genetic equilibrium.
