No Linkage of Yellow Body and Sepia Eye Mutations in Drosophila: Yellow Body X-linked and Sepia Eye Autosomal

Written by Brandon Abstract: The theory of independent assortment was first discovered by Gregor Mendel; however when the idea of genetic inheritance was revisited by Thomas Morgan, it was determined that it was not universally true of all alleles and for all organisms. Morgan’s experiments with Drosophila showed a difference in trait inheritance. Chromosomal Theory of Inheritance suggested that multiple genes are inherited in a linked fashion that is predictable and observable. This study focused to determine linkage between the […]

Mendelian Genetics with Drosophila

Written by Lauren  Objective: To explore the basic principles of genetics such as Medelian genetics using the model organism, Drosophila melanogaster. Introduction: Gregor Mendel, an Austrian monk, observed heritable traits in the common pea plant and discovered several key basic principles in Genetics. The pea plant was perfect organism for Mendel to observe because it reproduces quickly, and in large numbers, and is fairly easy to manipulate. What he discovered was that there are 7 inheritable traits that only have […]
