Fireflies Bioluminescence Lab

Suppose you have a flashlight in your hand. Describe the transformations of energy that take place to allow that flashlight to give off light. Be sure to include where waste energy is given off.

The firefly will move randomly if there are no fireflies brighter than that firefly. Objective function determines the brightness of firefly. The pseudo code for the FA is as follows: Algorithm: Firefly Algorithm Inputs: population size ‘n’, maximum generation ‘MG’ Specify initial values of alpha, beta and gamma Compute initial fitness of ‘n’ fireflies Identify initial best solution

Drosophila melanogaster may just be small little fruit flies that feed on rotten fruit but this little creature happens to be one of the most valuable organisms in understanding genetic research. The D. melanogaster are commonly used in studying genetic traits because they are useful, small and have an extremely short life cycle (6). Our experiment shows precisely how D. melanogaster are used to identify mechanisms of transmission genetics in eukaryotes. Simple parental crosses were done to obtain both F1 and F2 generations. This was done so we could determine if the apterous (a wingless phenotype) and the sepia (dark brown) eye color of the fruit flies follows Mendelian inheritance or not. Our F1 generation displayed all offspring with red-eyes and wings; which follows Mendel’s principles. Our hypothesis is that our experiment will follow the classic inheritance patterns because the sepia traits and the wing traits display a dominant/recessive pattern in the D. melanogaster (4). If our hypothesis is correct, then we predict to see an entire F1 generation of red eyed fruit flies with wings and an F2 generation of 9 normal

Gregory Mendel is the father of genetics, he was able to recognize to principles of inheritance: the law of segregation and the law of independent assortment. Fruit fly is a small type of fly; it is in most cases found near rotten or unripe fruits, this fly as been used extensively in genetics. Genetic recombination and sex linkage led to the use of drosophila in genetics also its relatively small size, sort generation time and easiness in culturing it.

9. Fourth week: Begin removing the F2 flies. Record their sex and the presence or absence of mutation(s). The more F2 flies collected, the more reliable the data will be. You may have to collect flies over a three-or four day period (or more). Try to collect at least 200 flies (probably quite a bit lofty).

In this experiment, two types of Drosophila melanogaster (fruit flies) were used: mutant and wild type. The wild-type flies had normal shaped wings and red eyes, while the mutant had either vestigial (short) wings or white (blind) eyes. The strains used for each mutation were W118 (white eyes) and strain 432 (vestigial wings). The flies with the vestigial mutation had the allele genotype of Vg-Vg- for female and the males had the allele genotype of Vg-Y. The flies with the white-eyed mutation had the female genotype of XwXw and the males had the genotype XwY. The population was created by crossing equal numbers of WT and Mutant flies. The populations were allowed to randomly mate for 10 generations in order to reach Hardy-Weinberg Equilibrium. We used half of the original population for the experiment and the other

Genetics is the study of genes, heredity and variation in living organism. It is important in understanding how heritable traits are passed down from one generation to another. Here in this study, the identification of a particular mutation was explored by discovering how it is transmitted and where it is located. Drosophila melanogaster, a species of fruit flies, was the model used to illustrate the process of gene inheritance. Virgin female fruit flies were collected over a span of two- three weeks and crossed with balancer chromosome male fruit flies. The progeny, also known as the F1 generation, was then used to perform a test cross. The test cross was done between an F1 male and a virgin female from the parental generation. The results of the test cross, determined the mutation as well as which chromosome it was located on.

to the measured data. Doing so may allow for further understanding concerning the possible errors

Fruit Fly experiment was conducted by using different techniques. One of the main things was to examine the fruit flies and identify the difference between females and males, identify their mutation if they were wild type, white eye, vestigial or white and vestigial combined together. These Fruit flies were kept in the incubator at 25°C for about 6 days. The main goal for this experiment was to observe the principles of Mendelian genetics.

1. Loosen the caps on the tubes of the cultures. Follow any instructions that are sent with the cultures to get them started.

Does the plant’s distance from the direct center of the LED lights affect its growth?

The purpose of our experiment was to see the progeny from the cross between the wild-type females and the mutant males and the cross between mutant females and wild-type males. We started by preparing the vials for the test cross. We had first prepare that inside the vials that will provide nutrients to the fruit flies so that they can carry out their life cycle. To do this, we obtained a clean vial and a foam plug. Next, a small scoop of powdered food was added to the vial. Then a small scoop of tap water was added. Once the mixed, approximately 4 grains of yeast were added. The vial was then tapped on the table to level out the mixture. The inside wall was then wiped with a clean Kim-wipe to keep the flies from sticking to the wall. This

Properly developed antennae of a fly containing different kinds of olfactory receptors allow the fly to use small amounts of smell for orientation towards resources like oviposition sites, food or mates. Scientists at one of the Chemical Ecology at Max Planck Institute in Jena Germany had used mutated flies and proved that the extremely sensitive olfactory system of the fruit flies.

Chemiluminescence is the release of light without heat due to a chemical reaction. The release of light is from bonds that are broken, formed, or restructured2. A similar process, known as fluorescence, also produces an illumination. This chemical process on the other hand, gets its energy for light from the absorbance and release of light at different frequencies.

Both the firefly and the firefly squid create light with a chemical called luciferin. When it combines with other chemicals, luciferin produces a light without heat. The structure of luciferin molecules in an animal’s body determines the color of the light – it
