Drosophila melanogaster lab experiment Question: How do the dominant or recessive genes in particular traits in a cross between a male and female Drosophila determine the traits of its offspring? in the December 2014 issue of GENETICS can be used to illustrate epigenetic modification of gene expression, reverse genetic manipulation, genetic/epigenetic influence on behavioral studies, and studies using the Drosophila model organism applied to human disease. Drosophila make good genetic specimens because they are small, produce many offspring, have easily discernable mutations, have only four pairs of chromosomes, and complete their entire life cycle in about 12 days. Objective: Students will learn and apply the principles of Mendelian inheritance by experimentation with the fruit fly Drosophila melanogaster. The cannibalistic tendency of Drosophila melanogaster larvae towards dead larvae led us to question whether adult flies, under starvation, can also feed on carcasses of Drosophila larvae.

What is it and why bother about it? Drosophila melanogaster Life Cycle (K. Weigmann et al, 2009) At the beginning of the experiment, the original stocks of flies (G0) were homozygous for either the red-eye (wild-type) or white-eye (mutant) phenotype, with red eye type being dominant to white eye type. Aim: to establish whether characteristics produced from the offspring of a drosophila cross are recessive or dominant traits. Drosophila melanogaster Life Cycle (K. Weigmann et al, 2009) At the beginning of the experiment, the original stocks of flies (G0) were homozygous for either the red-eye (wild-type) or white-eye (mutant) phenotype, with red eye type being dominant to white eye type. It is also one of the most valuable of organisms in biological research, particularly in genetics and developmental biology. Our new series, Animals in Research, profiles the top creatures for science experimentation, starting with Drosophila melanogaster – or, as you might know it, the fruit fly.

Since the

Thirty bottles with 30–60 individuals each (base population) were founded and maintained with circular mating until the start of the experiment in February 2008. Here, the goal was to develop techniques to measure endogenous … Drosophila Melanogaster has been extensively studied for genetic investigations due to its ideal characteristics for the study of animal development. A quick and simple introduction to Drosophila melanogaster. In this experiment Drosophila are use because they are small and easily handled, Drosophila are sexually dimorphic (males and females are different), making it is quite easy to differentiate the sexes, and flies have a short generation time (10-12 days) and do well at room temperature.
