Drosophila Lab Report Introduction: Gregor Mendel is the name responsible for the study of genetics (Campbell, Neil et al, 2005). He studied genetics using his two basic laws and the study of pea plants (Campbell, Neil et al, 2005). The first of his two laws was the Law of Segregation which stated that that there are two alleles and each one from the pair separates into a different gamete during reproduction. (Campbell, Neil et al, 2005). The second of his two laws was the Law of Independent Assortment and this stated that each pair of alleles separate independently. (Campbell, Neil et al, 2005). Mendel began the study of genetics using pea plants crosses and the punnett square. The punnett square takes the alleles from both sides and shows the cross and the results (Genetics of Drosophila melanogaster). Many scientists began to use this method for the testing of different species. (Genetics of Drosophila melanogaster). In 1907 T.H. Morgan began the testing of Drosophila melanogaster (Campbell, Neil et al, 2005) . Drosophila melanogaster are the flies often seen in the grocery store around the fruit. They are also known as fruit flies or vinegar flies (Hester, L et al, 2006). This fruit fly only eats the yeast on rotting fruit (Hester, L et al, 2006). Scientists picked the Drosophila to test in their experiments because it is very capable of reproduction and it is visible by the naked eye, but not too large that it takes up a lot of room and these fruit flies are very inexpensive (Hester, L et al, 2006). Many scientists also use fruit flies because they are very similar to humans, relating to disease and genes (Hester, L et al, 2006). Atleast 5,000 genes are shared between flies and humans and a female fly and a female human have about the same
