Biology 301 12/3/2012 The Effects of Relative Fitness of Drosophila Melanogaster on Evolution Abstract This experiment was conducted to study the relative fitness of two phenotypes of the Drosophila melanogaster and how fitness can affect evolution in the population. The phenotypes were placed in two different environments‚ one in which contained a predator and another with no predator. Results of the experiment would show how the fitness of each phenotype is affected by providing a mechanism

carriers for this trait since the recessive homozygotes are killed. The heterozygotes for the “L” allele are green since they produce chlorophyll. The aim of the Zea mays investigation was to distinguish lethal alleles by reviewing observing frequencies in growth. In order to do this‚ dominant and recessive alleles had to be observed. In Zea mays deleterious alleles cause a loss of function through the

developed a theory on evaluation. Their theory defines evolution as being the sum total of the genetically inherited changes in the individuals who are the members of a population’s gene pool. They observed that evolution is simply a change in frequencies of alleles in the gene pool of a population. Hardy and Weinberg‚ and the population geneticists who followed observed that evolution will not occur in a population if seven conditions are met: 1. Mutation is not occurring 2. Natural selection

Trading Report Strategy Chosen Our strategy is consisted of two parts: when the market is neutral without obvious trends‚ we play like the role of market maker; on the contrary‚ we put our bet on the trend. At first‚ we calculate the weighted average quantity from the order book‚ says 1st to 4th layer‚ for both sides. If bid quantity is larger than 2.5 times of ask‚ we believe that bulls prevail and this trend will be continued in a phase. Thus we place a market order to buy‚ expecting to earn

hemoglobin which may result in death. Allele frequency changes over time depending on the pressures or circumstances facing a particular population. African populations are especially impacted by both malaria and sickle cell anemia. Depending on the impacted population‚ allele frequency often shifts and well suited organisms are likely to survive and allele frequencies can increase. When a population is effected by disease or other circumstances‚ allele frequency may decrease or change. HbA (normal
