results were observed and recorded. Class data was also included in the results for comparisons. We found that though some of the results for each of the crosses were close to the null hypothesis‚ they did not accept the probability of the Chi-Square analysis. This means that even though there are expectations for the results‚ what happens in nature can almost never be controlled completely. Background The first experiments utilizing the fruit fly Drosophila melanogaster were performed by Thomas Morgan

CLUSTER ANALYSIS: ALGORITHMS AND ANALYSIS USING SAS BY: AHMED ALDAHHAN SUPERVISED BY: LECTURER JING XU BIRKBECK UNIVERSITY OF LONDON 2013/2014 ABSTRACT The scope of this paper is to provide an introduction to cluster analysis; by giving a general background for cluster analysis; and explaining the concept of cluster analysis and how the clustering algorithms work. A basic idea and the use of each clustering method will be described with its graphical features. Different clustering

Drosophila Melanogaster Introduction Drosophila mature through complete metamorphosis‚ as do all members of the order Diptera. [5] Diptera are commonly known as (true: having two wings) flies and include many familiar insects such as mosquitoes‚ black flies‚ midges‚ fruit flies‚ and house flies. [3] Drosophila melanogaster are most commonly known as fruit flies and are used in many genetic studies for a few simple reasons; they are small and easily handled‚ they have a short life cycle

When we started this lab the question (subject) we had to try and solve was ‘Which pattern of inheritance is present in the O’Smithsteinskis and AkimGarciaChan family pedigree? If when looking at the number of people shaded in our pedigree and find that the number is increasing each generationon then we can assume that the p
Premium Allele Dominance Zygosity
Extension of mendelian inheritance Incomplete Dominance Incomplete dominance is a form of intermediate inheritance in which one allele for a specific trait is not completely dominant over the other allele. This results in a third phenotype in which the expressed physical trait is a combination of the dominant and recessive phenotypes. Incomplete dominance is similar to‚ but different from co-dominance. In co-dominance‚ an additional phenotype is produced ‚ however both alleles are expressed completely

F1 offspring are all heterozygous‚ Cross F1 x F1 F2 generation shows individuals of both phenotypes‚ in a specific ratio 9:3:3:1 -this would only occur if independent assortment = 2 alleles separate & sort independently into gametes Mendel Rules of inheritance Different alleles for the same gene Principle of segregation-each gamete has 1 allele of each gene Principle
