Summary Introduction
To explain:
The way in which biologist identify the genes that control behavior in a fruitfly and the reason for why it might be difficult to identify the similar genes in humans.
Concept introduction:
There are certain structures that govern and control all the traits in an organism. They are called chromosomes. Chromosomes are the hereditary structures that have certain portions called genes. These are the actual structures on which entire hereditary traits and inheritance of traits depends as they are certain portions of a chromosome that code proteins.

- The homeotic mutation Antennapedia causes mutant Drosophila to have legs in place of antennae and is a dominant gain-of-function mutation. List all the properties of such mutations. How does the Antennapedia gene change antennae into legs?arrow_forwardMAKE A simple sketch and label characteristics Choose a human-related organism to study. As you consider strategies to enhance the social value of this organism, think of other desirable attributes that may be added to it. Imagination is a powerful tool, so let it go wild and imagine that you can transfer genes across other animals. For example: A gene from a firefly has been transferred into tobacco plants so that they may glow in the dark, as demonstrated by geneticists. Tobacco pests are less likely to attack at night because of this.arrow_forwardWhy are fruit flies considered a model genetic organism? Would humans fit this description?arrow_forward
- Why do queen honey bees (Apis mellifera) behave very differently from their workers even though a queen has essentially the same genome as her worker sisters and daughters? Develop at least one proximate hypothesis on why the two categories of bees behave so differently.arrow_forwardA graduate student performing studies on mutations in drosophila (fruit flies) discovered a strain of flies with a silent mutation in the gene controlling the shape of the wings. Further investigation has shown that this mutation is lethal in flies who are homozygote. Flies that are homozygote wild type or heterozygote can develop and are able to survive. What is a silent mutation (in your own words) and propose a hypothesis that could explain these observations using concepts learned.
