Genetics fruit fly experiment

WebIntroduction In this project, several aspects of Mendelian genetics will be investigated using the common fruit fly, Drosophila melanogaster (D. melanogaster). Normal wild type flies will be crossed with mutant flies and the pattern of inheritance of the mutations will be traced through F1 and F2 generations. WebFruit Fly Lab Report. The purpose of this experiment was to determine the F1 genotype of fruit fly traits using the phenotypic ratio of the F2 generation and to express these results of the unknown cross through a Chi-square model and Mendelian genetics. After the experiment, it was found that the parents held a heterozygous genotype through ...
