Essay on Hardy Weinberg Sheet - 644 Words

Biology Hardy-Weinberg Lab Using the Hardy-Weinberg equation, calculate the predicted genotype frequencies for each population scenario below. Place your calculations and data in the space provided below. Once you have calculated the frequencies, answer the conclusion questions for each one. Please remember that all calculations must be shown for full credit. Scenario #1 In the year 2050, humans have successfully colonized the Moon. The lunar modules created for this purpose could only house a small population of people. It is now a century later and the population has grown to 4,000 people. In the current Moon population, 10 people express the recessive phenotype for cystic fibrous (cc genotype). q2 – 10/4000 = 0.0025 q – √0.0025†¦show more content†¦No 2) Is the current population evolving? Yes 3) If the current population is evolving, what type of effect is responsible for genetic drift? The effect of genetic drift responsible is the bottleneck effect. Scenario #3 Sickle cell anemia is more common in sub-Saharan regions of Africa, where malaria is prevalent, than it is in regions where malaria is not common. This is because being heterozygous for sickle cell anemia in malaria-prone regions carries a fitness. A new malaria vaccine was introduced and given to all the people of Population A, which is located in one of the regions where malaria is most prevalent. Since the government wished to test the effectiveness of the vaccine, Population A was isolated; therefore, there was no migration in or out of the population. Every citizen of Population A was vaccinated when the experiment began, and every new baby was vaccinated immediately after birth. Allele frequencies were calculated every 20 years. After 100 years, 360 out of 1,000 people in Population A are homozygous recessive for sickle cell anemia (ss genotype). q2 – 360/1000 = 0.36 q – 0.36 = 0.6 p – 1- 0.6 = 0.4 p2 – = 0.16 2pq – 2 x (0.4) x (0.6) = 0.48 Conclusion Questions Use this information to help you answer theShow MoreRelatedGenetic Changes Within The Populations : The Consequences Of Selection1115 Words   |  5 Pagesallele and genotype frequencies for three generations of deer mice under three different selective regimes. Then, we use the Hardy-Weinberg Principle to assess the selection and evolution experienced by deer mice. The Hardy-Weinberg Principle is one of the most important principles in population genetic. G.H. Hardy and W. Weinberg discover it in 1908 independently. Hardy-Weinberg principle states that In a population that is not evolving, allele and genotype frequencies will remain constant from generationRead MoreManagement Course: Mba−10 General Management215330 Words   |  862 Pagesjust that. They sat down on the plaza right where they were, effectively blocking the car’s movement. The police and administration had never before confronted such massive defiance, and for 32 hours the car stayed put (with the â €Å"prisoner,† Jack Weinberg, inside) while demonstrators used its roof as a podium from which to speak to the crowd. One who climbed up to speak several times, and who clearly had a gift for energizing the crowd, was Mario Savio. In many ways, the Free Speech Movement, whichRead MoreStrategic Marketing Management337596 Words   |  1351 Pageswhich the environment affects strategy 2 Understanding the ways in which environmental pressures can be related to the capabilities of the organization. A possible danger that has been highlighted by several commentators is that of adopting a ‘balance sheet’ approach to environmental analysis – simply listing all possible environmental influences and then categorizing each as either an opportunity or a threat. If environmental analysis is limited to this alone, the strategist is left with far too broad
