Personal Essay On Fly Genetics

The experiment was performed on February 2nd 2016 at the University of Calgary in a Biological Science laboratory. The experimental procedure was done in a group of four students.

The basis of genetics were established by Gregor Mendel, an Augustinian monk in the mid to late 1800’s. Through the observations from cross-pollinating pea plants, Mendel was able to discover the basic laws of inheritance. Years later genetics would be studied on a multitude of organisms, some more than others. Drosophila melanogaster or the common fruit fly has been studied in depth for its great advantages, such as size, reproduction rate, ease of care and inexpensive room and board.

Supervisors and managers can encourage their employees to do things such as exercise (Wong, 2016) to help improve their mood, especially during significantly stressful times. Kinicki and Fugate (2016) wrote that emotions are products of our thoughts, behaviors, and experiences. They also wrote about some specific things we can do to manage our thoughts and behaviors to experience more positive emotions: manage expectations, take time to plan and organize, give a gift to other people, deflect partisan conversations, assume people have good intentions, focus on the job in front of you, and end the day with gratitude (Kinicki & Fugate,

When given the opportunity to do a task, the first step to ensure a desired outcome is to provide a positive attitude. A person’s attitude is capable of influencing not only one’s own performance, but also the actions of others being affected. For my Health Services Academy classes, we were recently assigned to do a project in which we had to diagnose a case study and develop an innovative treatment plan. As my group’s presentation approached, there was a specific day when all of my group members were feeling under extreme pressure and behaving in ways that they usually wouldn't. Despite my personal feelings, I managed to reassure my classmates and stay positive; consequently, everyone else’s moods seemed to improve as well. As an intern, I’d practice that same skill and contribute to a welcoming and

It would be expected that the mutant F1 flies would be heterozygous for the allele responsible for the grounded trait. If two F1 flies were mated, the percentage of flies that would be expected to be wildtype in the F2 generation would be 25% mutants given that the mutant allele (ap) is predicted to be recessive and, leaving 75% to be wildtype (ap+).

Environmental conditions are sometimes appropriate for the evolution of numerous species from a common ancestor. Evolutionary, or adaptive, radiations happen when a large number of species descend from one lineage. This phenomenon usually occurs when a population of one species colonizes an area with many available ecological niches and when the rate of speciation is greater than the rate of extinction in a given area. Adaptive radiations have historically taken place after mass extinctions and on newly formed island archipelagos, because these incidences create conditions where new species can fill open ecological niches. Unlike the mainland, ecological niches are available on new island systems. These island species adapt to new environments

19) Collect 5 males and 5 females of the F₁ generation and place them in the vial to become parents of the F₂ and seal it with another plug.

Genetics shows us that we inherit traits in many different ways. A perfect example to show us the different ways we inherit traits is fruit flies. Fruit flies are commonly used by scientists to conduct genetic experiments due to their reaction to the experiment being very quick. Scientists mainly look at how the flies inherit basic traits such as brown body color, or red eyes(basic trait flies are known as wild-type flies) from their parents, but sometimes they can come across some abnormal traits. Some of these abnormal traits include having a yellow body color or having curly shaped wings and have made scientists wonder how the flies have inherited these specific traits. So how do the flies inherit

Marcum’s class, so when I actually got to experience a suspect being processed I found very informative. This experience has influenced my opinion on theories and education studying Criminal Justice. I think it is the utmost important to have future officers obtain as much education as they can, because it will help eliminate future incidents like what we have seen recently in the news. I also believe what Dr. Robinson taught us that families and friends are the single most influential group while growing up. That when a child is growing up they need stability in their lives and a loving family, I saw this first hand while patrolling the streets with officers and detectives that different demographics of family living situations were going to determine the likelihood of their own child participating in illegal acts. While being one of the lucky individuals that was selected to intern with Raleigh I have learned a great deal. These detectives I worked with gave me great insight on day-to-day activities. One detective gave tips on interviewing suspects like: body language, eye contact, arms being crossed. The detective also told me to watch the person’s facial expressions when presenting a picture because there expression will usually indicate if they

Fruit flies with normal wings have a higher population and greatly outnumber the population of fruit flies with dichaete or vestigial wings.

Gregor Mendel, the father of genetics, discovered principles of inheritance through breeding peas of different color and texture. He crossed several types of peas to investigate dominance relationships, variability, and genetic probability. Through his experiments, he laid down the foundation of inheritance that geneticists use to this day (Griffiths, 2015). From these crosses, Mendel pioneered modern genetics by developing seven laws of inheritance. The first and second law are investigated in this experiment.

we said goodbye and placed them in the fly morgue. We allowed the F2 larval

The major topic of this experiment was to examine two different crosses between Drosophila fruit flies and to determine how many flies of each phenotype were produced. Phenotype refers to an individual’s appearance, where as genotype refers to an individual’s genes. The basic law of genetics that was examined in this lab was formulated by a man often times called the “father of genetics,” Gregor Mendel. He determined that individuals have two alternate forms of a gene, referred to as two alleles. An individual can me homozygous dominant (two dominant alleles, AA), homozygous recessive, (two recessive alleles, aa), or heterozygous (one dominant and one recessive

These words, printed on a black poster and hanging on the door of the biohazard lab, mocked me mercilessly as I frantically ran around swatting fruit flies with my bare hands. My lab partner, Becca, and I had avoided a fly infestation this far into our multi-month long experiment, and now, on the last day, the impending accomplishment of that one solitary task hung over our heads.

I assist a graduate student in a biology lab working to find genes and mechanisms involved in sperm competition between different strains of Drosophila. I have worked ten hours a week this summer and will continue with those hours during the coming school year. My tasks include identifying and separating individuals by sex, setting up crosses and dissecting males to determine their fertility. Much of what I do requires fine motor skills, attention to detail and a good deal of patience because there are so many tiny flies and larvae to count and handle. The experiment has proven very educational, and I have learned much about fly genetics and evolutionary processes.
