Virtual Fly Lab
If your knowledge of Genetics is minimal you may want to take a look at the Genetics info in BIO 113 before beginning the Virtual Fly Lab.
BIO 114 Virtual Fly: To begin your experiment, you must first select the phenotypes for the flies that will be mated. In addition to wild-type flies, there are thousands of different mutations of the common fruit fly, Drosophila melanogaster. These mutations create phenotypic changes in; body color, antennae shape, eye color, eye shape, wing size, wing shape, wing vein structure, wing angle and many other features. For the purposes of our simulation, genetic inheritance in our virtual lab will follow Mendelian principles of complete dominance.
The phenotypes we will use in this virtual Lab are Apterous (No real wings) and Vestigial (very small wings). These are common mutant phrnotypes, variations in wing size. Vestigial and Apterous are recessive traits, so flies with either vestigial or apterous wings must be homozygous recessive (e.g. (v, v) or (a, a) ). The wild type flies we are using are Homozygous dominant (in fly genetic notation this is written as (+, +) ). Heterozygous flies could be either (+, v) or (+, a). To understand the genetics you should always keep track of both the Genotype and the Phenotype of your flies and their progeny (kids).
