Introduction Drosophila Melanogester (Fruit Fly) is a common bug that can be found just about everywhere. They are good genetic model organisms with a low number of chromosomes and the breed fast and also have trackable mutations. Their new generations are created in only 10 days, spending 1 day as an egg, 5 days as a larvae, and 4 days as a pupa, with the ending result being a grown fruit fly. Alleles are forms of a gene, there are two types of alleles, dominant which is highly expressed and recessive which is not expressed. They can be displayed most simply through punnett squares. Purpose The purpose of this experiment is to allow the students to learn about punnett squares and how they work and about the fruit. Also to gain practice successfully filling in one, and being able to figure out the genotype and phenotype. Materials
