Textbook Question
Chapter 1, Problem 8CONQ
Your textbook describes how the detrimental symptoms associated with the disease phenylketonuria (PKU) are caused by a faulty gene. Even so, a change in diet can prevent these symptoms. Pick a trait in your favorite plant and explain how genetics and the environment may play important roles.

In Genetic Variation, If people have a similar genetic makeup, why do weu use DNA to understand or determine whether suspects are innocent or guilty of a crime.
in a summary use your understanding of molecular biology to explain that recessive alleles are expressed through transcription and translation, and that they may have functional gene products. Describe how the interaction of the products produced by each allele results in what we see as dominant or recessive traits.
Imagine you are working in a genetics lab with the fruit fly Drosophila melanogaster, a model organism for genetics research. You want to determine whether a trait you have discovered in fruit flies is dominant or recessive.• Explain how you would design an experiment to answer this question.

- If you were to choose between a fruit fly and a mouse for an experimental organism in genetics, which would you choose? List down five reasons for your answer.arrow_forwardExplain the relationship between a mutation, a protein, a trait, as well as dominance and recessivity of an allele. You may use the example of the taster gene that you examined in your practical if you wish.arrow_forwardOften successful domestication of a plant or animal is due to the fact that this involved just a few gene changes. In what situation can changes in just a few genes dramatically change an organism's entire appearance?arrow_forward
- How can you use this piece of information to help you explain to your friends what is the significance of mutations in the emergence of new genetic properties (alleles) that may result (or not) in new phenotypic characteristics? (Recall that not all SNPs affect phenotype.)arrow_forwardWrite the name of the term that describes the phrase.

Why was that organism a good choice for the experiment?arrow_forward
- What is the difference between a gene and an allele? a. A gene is a form of a trait, and alleles make up genes. b. A gene is a sequence of bases in a DNA molecule, and an allele is an alternative version of a gene that codes for the same feature. c. A gene is a sequence of bases in a DNA molecule, and an allele is an alternative version of a gene that codes for a different, but related, feature. d. A gene describes a chromosome, and an allele describes an exact location of a gene on a chromosome. e. An allele and a gene are the same thing.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_forwardHow can mutations cause changes to the traits? Explain using the following steps:1- DNA 2- Gene 3- Protein 4- Traits We need one explanation for the normal side and one for the mutation side. Can you explain in a few sentences how the change in the structure of the gene affects the function of the corn plant?arrow_forward
- Can a change in a protein's shape affect a trait? Why or why not? Group of answer choices 1. Yes, because shape determines function and traits come from proteins 2. No, because proteins are not related to traits, only DNA is 3. Yes, because proteins are the template to build DNA, which controls our traits 4. No, because shape is not related to function, so will not affect traitsarrow_forwardgive three examples of the role of genetics in society todayarrow_forwardMany different traits in the human race are the result of recessive or dominant inheritance. Select a trait from the list below and create a family pedigree chart for the trait. Complete at least three generations . You may use your own family, a friends family or a famous celebrity family to create your pedigree.arrow_forward
