The fruit flies does deal with dominant vs. recessive for the wing traits. Complete dominance occurs when the dominant allele complete cover (hide) the recessive allele. This occurs to the wing traits in the fruit flies. Normal wings are dominant over vestigial wing and base on the data, the female that carries the vestigial wing did not create any F1 generation of vestigial traits. This occurs because the male has normal wing so when the two parent meet; the dominant normal wing in the male completely cover up the recessive vestigial wing in the female traits. The data was able to support the statement above because based on the data, there was only two phenotype and they both have normal wing for the male and the female.

Since we have six different type of phenotype for the result for the F2 offspring, six would minus one therefore the the number of degree of freedom being used for the lab report would be five degree of freedom.

The Chi square number for the fruit flies problem is 0.795.

The number 11.072 determined whether the hypothesis is supported or not supported because based on Chi square 5% or less is not supported while a higher percentage of five is supported by the hypothesis.

The hypothesis for the genotype and phenotype of the fruit flies was supported by the data. The hypothesis has 70% or higher meaning that the hypothesis is supported by the data. Even though, the hypothesis was supported mathematically, it does not guarantee that it is 100% correct.

One thing learned about genetics through the fruit flies problem is that fruit flies also have sex-link traits similarly like the human. For example, the eye colors in fruit flies and the color blindness for the human traits; both sex-link traits are determined by the female allele therefore most of the male are the one that carries these

    Introduction Fruit fly Drosophila melanogaster that is used as a model to study genetics for more than a hundred years. Thomas Hunt Morgan, in the early 1900’s, used the heritable traits of a common species of fruit fly to develop our understanding of genetics. Morgan was the first to show through experiments that genes were located on chromosomes. He also found that certain fruit fly traits like eye color are found on the same chromosomes that also determine their sex. Fruit flies have several characteristics…

    internship working in Paul Garrity’s behavioral biology lab at Brandeis University and conducted experiments on genetically modified common fruit fly, Drosophilia. There I learned about the important research that is being done on these fruit flies throughout the country and the burgeoning science of genetic modification that has begun dominating laboratories across the country. This research focused in on the sensory receptors that the flies use to detect changes in humidity and temperature. Using…

    Introduction: Drosophila melanogaster, which commonly is known as fruit fly, has been used in genetic study for centuries. They tend to give birth to a large amount of offspring while their life cycles and generations are short. Their genes can be mutated easily by radiation or mutagens in food. They have four large chromosomes with approximately fourteen thousands genes. As expected, human have several times more gene than D. melanogaster, however, we have almost the same number of gene families…
