    A Study Of Inheritable Traits in Fruit Flies INTRODUCTION The Drosophila melanogaster, more commonly known as the fruit fly, is a popular species used in genetic experiments. In fact, Thomas Hunt Morgan began using Drosophila in the early 1900's to study genes and their relation to certain chromosomes(Biology 263). Scientists have located over 500 genes on the four chromosomes in the fly. There are many advantages in using Drosophila for these types of studies. Drosophila melanogaster can...

    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...

Instead, we see that its offspring is purple as well. This is led to be by one trait being dominant over another trait.

Thomas Hunt Morgan, who lived from 1866 to 1945, was the founder of drosophila genetics. Thomas preformed his research in Morgan lab at the Columbia University in 1910. Here was when they found a famous mutation, know as the white-eyed fly. Quite an accomplishment was this discovery, but the end of the 1980's there were 3,000+-recorded mutations.

The main cause of this was the fact that the fly vials were stood up (vertically) before the flies had fully recovered from the anaesthetic.

One possible error that may have occurred was that some of the adult flies may have accidentally been left in the vials...
