Fruit fly - Lab Report ExampleOn the other hand, the life bicycle of the fruit fly is normally short. In this respect, it lasts for about 26 and 33 days for females and male flies.The life cycles could also be changed depending on the environment or specific mutations of genetics. At room temperature, the flies may take 10 days from egg to adult. This makes the fruit fly to be the best subjects for a search on genetics since multiple gene confine could be studied for a short duration of time. The fruit fly life cycle begins whenever an egg is primed(p) by a female that is impregnated. The fly only gives out one egg at a moment. The hatching of the egg occurs within 22 hours, and the larvae jump on in a period of four days (Manning 8). After this, the larvae would follow three stages up to the pupa stage. In this stage, pupal case is established, hardens and darkens in duration of 4 to 6 days. Lastly, the pupa changes to the adult stage. The male fruit flies have a body that is sm all with a black tip on their bodys end. The female fruit fly do have an abdomen that is pointed and are light compared to males. The prime objective the experiment involves the performance of a di crossbred cross.Flies that were hybrid for two traits (dumpy wings or normal wings, black or normal body) together with two different eye color (wild red type and mahogany tree brown) were provided for the experiment. The two were produced through the crossing of homozygous sepia-eyed flies, normal-winged, red-eyed flies and with dumpy. Prior study have shown out that dumpy wing mutation is an x-linked trait that is recessive thus carried by the x chromosome that determines the sex. Through a punnett square for the initial generation, the genotype that is expected and the ratio phenotype could be found. This is displayed in table 1.According to the table, 1, it is certain that the phenotype ration of the first generation is dumpy wing, half male, half female. This information can be use d to generate a second punnett
