interest. The closest organism that was similar was Drosophila melanogaster that had the highest max score of 4405 and an ident % of 100 ant an e-value of 0. This shows that it is the most similar organism in the Gene 2 to the Gene sequence of interest. This spicies is located on the top of the insect branch of the cladogram because the most similar organism is a fly. From my data the second most similar Gene sequence that was absorbed was the Drosophila sechelia that had a max score of 648 but ident

The Cross between Wild Type And Ebony Introduction: In 1909‚ Professor Morgan studied genetic change with Drosophila melanogaster‚ or fruit flies. Because of him‚ fruit flies have become popular for genetic research. Since fruit flies have a high reproductive rate and short life cycles‚ they are ideal for the study of genetics. The generation takes about 10-15 days to be complete depending on the temperature. Ideal temperatures range from 20-25°C‚ where 25° reduces the days it takes for an

Epidemic Parotitis Fever‚ muscle aches‚ loss of appetite‚ exhaustion‚ swollen salivary glands‚ these are all possible symptoms of mumps‚ also known as epidemic parotitis (Mumps‚ CDC). All of these symptoms are caused by a viral infection;there is a vaccine to this virus to help protect humans from the horrible disease. The mumps virus‚ once inside the body‚ will spread to the throat‚ nose‚ mouth‚ and salivary glands by way of mucus and saliva. While it spreads‚ it can cause the symptoms previously

In addition to wild-type flies‚ 29 different mutations of the common fruit fly‚ Drosophila melanogaster‚ are included in FlyLab. The 29 mutations are actual known mutations in Drosophila. These mutations create phenotypic changes in bristle shape‚ body color‚ antennae shape‚ eye color‚ eye shape‚ wing size‚ wing shape‚ wing vein structure‚ and wing angle.

important parts. Along with this the chemical process also begins where your salivary glands start to produce saliva. Technically the salivary glands tend to get activated upon smelling the food‚ therefore your mouth starts to water. Saliva‚ which is a mixture of enzymes and water created by the cells in the epithelial tissue lining the mouth‚ keeps the mouth and other parts moist throughout the process. The salivary glands also help break down carbohydrates and lubricate the passage of food down from

The purpose of this experiment was to determine if two selected traits of Drosophila melanogaster‚ dumpy wings and sepia eyes‚ follow Mendel’s Laws of Inheritance through the F2 generation. Materials and Methods In week one‚ two crosses were set up. Dumpy females were crossed with sepia males‚ while dumpy males were crossed with sepia females. The dumpy phenotype consisted of shorter‚ smaller wings while the sepia phenotype consisted of brown eye color. For these crosses‚ all females were virgins

Sjogren syndrome is a chronic‚ slowly progressive‚ inflammatory autoimmune disorder characterized by dryness of the mouth and eyes. This autoimmune illness features inflammation in the lacrimal and parotid glands. The inflammation in the lacrimal gland leads to decreased water production for tears‚ causing dry eyes. The inflammation in the parotid leads to decreased saliva production in the mouth‚ causing dry mouth and dry lips. The two distinct forms of Sjogren syndrome are primary and secondary

To start this process‚ we have to start with the mouth‚ when food is put in to the mouth you start the process of digestion‚ the structure of the mouth is made up of the lips‚ teeth‚ tongue‚ salivary glands‚ soft palate and pharynx. The lips function is to hold food in. The salivary glands‚ there are three
