A Study Of Inheritable Traits in Fruit Flies INTRODUCTION The Drosophila melanogaster‚ more commonly known as the fruit fly‚ is a popular species used in genetic experiments. In fact‚ Thomas Hunt Morgan began using Drosophila in the early 1900’s to study genes and their relation to certain chromosomes(Biology 263). Scientists have located over 500 genes on the four chromosomes in the fly. There are many advantages in using Drosophila for these types of studies. Drosophila melanogaster can

[Untitled] Jana strolled beside Alo beneath the shady canopy until they came to the edge of the trees‚ where the forest gave way to a clearing. Alo stopped and she almost ran into him. She stepped around him and gaped—there‚ in the middle‚ stood a huge tree branching far overhead. At first‚ Jana thought it might be a giant ash‚ its towering trunk certainly reminded her of one. But it also had gnarled branches that sprouted out much closer to its base than a giant ash should‚ deep green leaves speckled

My tropical rainforest insect is the goliath beetle.Goliath beetles are one of the heaviest insects in the world. In my 3 body paragraphs i will tell what it eats‚ when does it search for food‚ what are its predators and how does it avoid them. Its scientific name is Goliathus. Goliath beetles can be found in many of Africa’s tropical forests. My first body paragraph is about what the goliath beetle eats. Goliath beetles eat different types of plant material‚ fruit‚ dung and remaining of dead animals

Abstract The basic principle of Mendelian inheritance was studied using the fruit fly‚ Drosophila Melanogaster. A Cinnabar Brown female was crossed with Wild Type male. The flies were mated in a jar containing a nutrient medium and then placed in an incubator. The experiment was conducted over a period of 5 weeks. Cinnabar (cn) and brown (bw) are two loci in Drosophila with recessive eye colour mutations. Mutations in cn cause a bright red eye and mutations in bw cause a brown eye. Double mutants

In the alpine regions of the Qinghai-Tibetan Plateau it was widely used as a food source‚ when other crop production was limited approximately 2000 B.C. These highlands range in altitude between 3000-4000 m and are characterized

Drosophila melanogaster is a fruit fly‚ about 3mm in length‚ and it is the insect that flies around spoiled fruit. A model organism has these traits: short life cycles and rapid development‚ small average size‚ big population‚ and fast reproduction (NCBI). Drosophila melanogaster meet all of the criteria for being a model organism. Also‚ fruit flies were used because they are very easy to handle and they require minimal resources to survive‚ as opposed to other organisms that might need more food

In John Steinbeck’s story “The Chrysanthemums” the main character Elisa is in the garden wearing men’s clothing; her appearance made her seem strong. "Her face was lean and strong and her eyes were as clear as water"(Steinbeck 226). Elisa has a strong self-confident attitude in the beginning of the story before meeting the pot fixer‚ and by the end of the story she lacks confidence and feels like she is losing control. In the beginning‚ Elisa likes the power she has over the chrysanthemums. The
