transmission of genetic traits by experimenting with pea plant breeding (1). By cross-fertilizing tall and dwarf plants, Mendel discovered genes that were expressed factor as dominant and the latent factor as recessive (2). These dominant and recessive forms are called alleles which are alternate forms of a gene. To study the inheritance of traits, Mendel did a monohybrid cross. A monohybrid cross is a cross between parents “differing in only one trait or in which only one trait is being considered”
Introduction Drosophila melanogaster, also known as the fruit fly, is an extraordinary organism that has been used for genetic experimentation due to its fast life cycle and the fact that it is very inexpensive to acquire and feed. The Drosophila life cycle is short and completed within 10-15 days. It begins with an egg that produces larvae, becomes pupa and eventually develops into an adult. After roughly ten hours after emerging, adult flies are ready for mating. 24 hours after mating, the females
with the particulate theory of inheritance and how traits are passed from parent to offspring. According to author Robert Brooker, traits are defines as genetically determined chracteristics; some examples of the first traits studied in humans were polydactyl and hemophilia. (Brooker, 2014). Traits of organisms are controlled by genes; genes are the section of a DNA on a chromosome which encodes for the formation of proteins which controls traits. There are three main type of
