Introduction
Evolution is the process in which organisms change from one generation to the next over a period of time. The Hardy-Weinberg equation is one of the most popular ways to determine if a certain trait within a population is changing. The Hardy-Weinberg equation provides a null-hypothesis to compare to the observation of the population. One can predict the outcome of the estimated amount of offspring in a population by using two alleles to determine which will be present in future generations. This equation uses a Punnet Square that makes a mathematical format to interpret the information. This possibility is referred to as Hardy-Weinberg equilibrium or Hardy-Weinberg principle. Although the Hardy-Weinberg equilibrium is rarely met in a given population, it can occur if only the allele and genotype remain the same from one generation to the next in the absence of different evolutionary influences. Alleles are a pair of genes that appear on a particular chromosome and control certain characteristics, such as color and …show more content…
It takes the Drosophila flies 24 hours after fertilization to go from an embryo to larva. The larva will eat and then continue to grow, taking about 6-8 days to become a pupa. During this phase, the pupa will undergo metamorphosis and change into an adult fly. The adult fly can live up to 8 weeks, which makes the perfect candidate for research studies. In this experiment two alleles will be examined, Wild type (+) and Ebony (e). These alleles determine the color of the flies when they are mature adults; wild types will have a tan body and ebony types will have a brown body (Nozawa, K, 1963). Keeping all of the following information in mind, the hypothesis is that the population of flies will fall within the Hardy-Weinberg equilibrium over three generations and the wild allele will be more dominant and prevalent than the ebony
