Fruit Flies Characteristics

“Who made what?” After learning the different variations of genetic traits passed down to the offspring, my team and I were influenced to conduct research regarding the genetic variations of fruit flies. “Which mode of inheritance do the yellow body and curly wing trait follow?” After coordinating research, it is evident that: Because only 2 yellow bodies can only reproduce other yellow bodies, Curly wings can have either Curly or Wild-wing off spring, and the characteristics of dominant and recessive genes, the yellow body genetic trait is a sex-linked recessive trait---while the Curly Wing genetic trait is a Dominant allele trait. In genetics, recessive and dominant genes are key factors in determining the phenotypes and genotypes in the offspring. Dominant genes are the expressed trait shown in the offspring, meaning if two alleles of a pair differ, the dominant gene is the gene that determines the phenotype and genotype. The recessive gene is the masked trait, meaning if two alleles of a pair differ, the recessive gene is the trait that …show more content…
The second generation offspring consist of: 12 wild and 40 curly males, with 6 wild and 37 curly females. Crossing the Curly Winged and Wild winged fly, produced both curly and wild offspring, but only in the second generation did wild winged flies show. The Curly winged fly can produce both Curly Winged offspring when both parents are homozygous curly; it can also produce wild winged offspring when both parents are heterozygous. A Dominant parent can have both recessive offspring, (if and only if both parents are heterozygous or if one parent is heterozygous and the other is recessive) and dominant offspring. Therefore, the Curly winged gene is a dominant trait, because it can produce curly and wild winged

    Without wings, the fly will have great difficulty escaping any dangerous situations such as predators or drowning and it will also struggle with courting (because they cannot make the sound with their wings) and mating. There is still a significant amount of research that can be done on this gene. The numerous interactions can be more closely studied in order to understand the true extent of dpp’s effect on development. In addition, because dpp plays such a vital role in development across taxa including in sea anemome, frogs, and humans, research could be completed to better understand development and possibly assist in the rapidly developing field of in vitro fertilization in humans. In addition, this gene may be studied to see if it has as significant effect, as it does in drosophila, on adult appendages.…

    We hypothesized that curly wing flies would have difficulty courting past the flapping of its wings to create a “love song”. The FraxE flies are model organisms of a mutation that causes mental retardation and various behavioral problems. We did not expect very much courtship at all in this group. Lilli flies were similar to the FraxE model except they had the protein that was lost with the mutation placed roughly 50% back into them. We thought the flies with this mutation would have more courtship then the FraxE but less than the curly wing fly.…

    Fruit flies are used in genetics and biological research because they are cheap and be quickly cultured. The use of the Pearson’s fly lab was pre-assigned for the physical experimental procedures to produce results in a limited time frame and reduce the chance of fruit flies contaminating the lab from student error. In order to test the hypothesis, I would observe the F2 generation. The initial parent cross takes approximately two weeks prior to produce the F1 generation. This parental cross would be of a homozygous recessive female (bb) with either a homozygous dominant male (BB) or dominant male with only one allele (XB Y).…

    The Br3 gene provokes a conjoined gene duplication which results in the malfunctioned process of crossing over (Zhang 2003). The genes being linked in the chromosome can contain an entire gene, a segment or none at all. Altering gene dosage is rarely tolerated by any other organism that is not a plant; organisms such as Drosophila have to adapt to these conditions and continue their pupae development into adulthood. Those flies affected by this particular allele will result in the elongated/ narrow tube-like eye shape.…

    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.…

    There is still a chance that it will not be passed down, but more than likely it will be. With that though, if the alleles that are being passed down are both dominant; than the alleles are both shown and that is called codominance (Barekzi, 2016). There are two other possibilities for dominant traits as well. Those are complete dominance and incomplete dominance. Complete dominance is when the offspring only looks like one of their parents and not like the other and incomplete dominance occurs when the offspring does not look like either one of its parents (Barekzi, 2016).…

    For this lab we conducted a population genetics study on the frequency of wild and apterous flies within a small population of fruit flies. The fruit fly Drosophila works well for genetic and evolutionary geared studies because they have a relatively short generation time but are intricate enough to reveal some biological principles that are parallel to many different kinds of eukaryotic organisms. When exposed to artificial selection in laboratory experiments, fruit flies have experienced dramatic changes behavioral and evolutionary traits within ten generations or less (Goldsmith, 1991). It is important to note that wild flies have wings and apterous flies do not. The purpose of artificial selection is for humans to modify species over generations by intentionally breeding two organisms with the objective of acquiring a specific trait.…

    Inherited traits put growth and development into action in not only individual organisms but also the evolutions of species over time. Humans wouldn’t have evolved to who we are now if it wasn’t for inherited traits. In fact all species have adapted and evolved to be unique and distinct. For example a hummingbird that has adapted to have longer bills to be able to reach inside a flower to get nectar. Hummingbirds could die out from having short bills so they evolved throughout generations.…

    The apterous gene mutations is a recessive trait that is inherited causing a varying phenotypes such as different wing deformities. Other phenotypes observed are the decrease in life span and female sterility. Ap is required to regulate gene expression needed for the development of Drosophila wings and haltere discs. Decreased ap activity due to the overexpression of dLMO results in wing mutations. The phenotypes displayed in apterous mutants are places them at a disadvantage compared to wild type flies.…
