Examining the Crosses Between Drosophila Fruit Flies Essay -- Fruit Fl

Examining the Crosses Between Drosophila yield Flies Introduction The major topic of this experiment was to examine ii different crosses between Drosophila fruit flies and to determine how more flies of each phenotype were produced. Phenotype refers to an privates appearance, where as genotype refers to an individuals genes. The basic law of genetics that was examined in this lab was hypothesize by a man often times called the father of genetics, Gregor Mendel. He determined that individuals have twain alternate forms of a gene, refer passing to as two alleles. An individual can me homozygous predominant (two dominant alleles, AA), homozygous recessive, (two recessive alleles, aa), or heterozygous (one dominant and one recessive allele, Aa). There were haul particular crosses that took place in this experiment. The first cross-performed was Ebony Bodies versus Vestigle Wings, where Long go be dominant over short wings and normal bodies are dominant over black bodies. T he other cross that was performed was White versus ferocious where red eyes in fruit flies are dominant over white eyes. The purpose of the first experiment, Ebony vs. Vestigle was to consider how some(prenominal) of the offspring had normal bodies and normal wings, normal bodies and vestigle wings, pitch black bodies and normal wings, and ebony body and vestigle wings. The purpose of the second experiment White vs. Wild was to see how many of the offspring were red eyed male, white eyed male, red eyed female, and white e...
