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

allele frequencies and I was able to calculate the observed relative frequencies by solving for p and q. The frequency of p was 2 times the 13 p alleles plus the 5 alleles from the heterozygotes divided by a total of 42 alleles in the class. The calculated p frequency is .738. The frequency of q was 2 times the 3 q alleles plus the 5 alleles from the heterozygotes divided by the total 42 alleles. The calculated q frequency is .262. The two frequencies sum to 1. The expected relative frequencies then

Customer Satisfaction of Nokia Mobile Project Abstract The main objective of the project is to study the satisfaction levels of customers‚ Product awareness and Consumer Behavior with reference to NOKIA mobile handset users. Nokia has played a pioneering role in the growth of cellular technology in Pakistan‚ starting with the first-ever cellular call more than a decade ago‚ made on a Nokia mobile phone over a Nokia-deployed network. Nokia started its Pakistan operations in 2000

Q. Explain the term Sampling distribution The term sampling distribution refers to a frequency or probability distribution of the sample statistic obtained from all the possible samples of size n taken at random from a given population. The sample mean (x) shows the average value calculated from measurements of a sample. Its main characteristics are: 1. The average of all sample means should equal to the true population mean (µ) 2. The standard deviation shows dispersion

unknown cross through a Chi-square model and Mendelian genetics. After the experiment‚ it was found that the parents held a heterozygous genotype through using the Chi-square model‚ and that the observed and expected values fall within the Chi-squared value which also falls into the p-value. The Chi-squared value was 5.64‚ the degrees of freedom was 3 and the p-value was between .05 and .2‚ which supports the failing to reject the null hypothesis. The results also yielded the expected 9:3:3:1 ratio showing

to grow then cross-pollinating the F1 plants to produce the F2 seeds. Next students were to plant the F2 seeds and record the phenotypes. After all the data was collected we ran a statistical test called a Chi Squared to see if the hypothesis put foreword was correct. After running the Chi Squared Test the Group and Class hypothesis was accepted. So in conclusion the fast plants resemble Mendel’s genetic experiments.
