Drosphila melanogaster (fruit flies) and set up genetic crosses in order to determine the pattern of inheritance of certain mutant traits. The traits for which we will examine the pattern of inheritance are apterous (wingless)‚ vestigial (crippled wings) or white eyes. These are all mutant strains. The normal condition (winged and red eyes) is referred to as the wild type strain. Objective: The intial cross mates homozygous mutant fruit flies with homozygous wild type fruit flies in order to produce

They were all later accredited with the Nobel Prize in physiology and medicine in 1962. Thanks to their discovery‚ science has been able to research and learn from DNA blueprints and use recombinant DNA technology to discover answers‚ vaccines and build immunity for many viruses. In recent years science has been using this new technology to genetically modify animals
