Which of the following is an example of environmental impacts on the expression of traits? Animal coat color shifts in response to seasonal changes in day length and temperature.
Which is an example of the environment influence the expression of a genetic trait?
Drugs and Chemicals
The presence of drugs or chemicals in an organism’s environment can also influence gene expression in the organism. Cyclops fish are a dramatic example of the way in which an environmental chemical can affect development.
Which of the following is an example of the environment affecting the expression of a gene and the phenotype?
Environment Can Impact Phenotype
Environmental factors such as diet, temperature, oxygen levels, humidity, light cycles, and the presence of mutagens can all impact which of an animal’s genes are expressed, which ultimately affects the animal’s phenotype.
How can environment influence traits?
Explanation: Environmental factors influence traits in plants and animals. These traits include things like weight, height, size, and color. If a child does not get proper nutrition, their height may be stunted as an adult.
What are the factors that influence how traits are inherited?
Various factors, including genetic makeup, exposure to harmful substances, other environmental influences, and age, can affect expressivity. Both penetrance and expressivity can vary: People with the gene may or may not have the trait and, in people with the trait, how the trait is expressed can vary.
Which of the following is an example of environmental impacts on the expression of traits quizlet?
Which of the following is an example of environmental impacts on the expression of traits? Animal coat color shifts in response to seasonal changes in day length and temperature. The distribution of the data in a graph showing the relative abundance of human height phenotypes follows a bell-shaped curve.
What are environmental influences on child development?
Social environmental factors that influence a child’s development are derived from their cognitive and educational attainment, risk-taking behavior, emotional, psychological well-being, motivation and physical health in addition to parenting and family impact.
Which of these is an example of an environmental effect on phenotype?
Environmental conditions, such as temperature and availability of nutrients can affect phenotypes. For example, temperature affects coat color in Siamese cats. … Height in humans is a complex phenotype influenced by many genes, but it is also influenced by nutrition.
What are some examples of genotype environment effects?
Below are some known gene-environment interactions that increase the risk for specific disease outcomes.
- Organophosphate Pesticides and Parkinson’s Disease. …

- Asthma and Air Pollution. …
- Esophageal Cancer and Alcohol.
What are examples of environmental traits?
Examples of environmental traits are your favorite music, being a good basketball player, and the language you speak. These traits are environmental traits because they are traits that you choose or learn, or that are influenced by the place you live. Explore the inherited traits and learned behaviors of a classmate.
What affects our traits?
Individuals get one copy of a gene from each parent, but the interactions between the genes influence how the trait is expressed. … Most traits are influenced by many genes, there are many different ways for those genes to influence how the trait is expressed.
What are environmental threats?
The main dangers worldwide are population growth and resource consumption, climate change and global warming, habitat conversion and urbanisation, invasive alien species, over-exploitation of natural resources and environmental degradation.
What is trait expression?
The observable traits expressed by an organism are referred to as its phenotype. An organism’s underlying genetic makeup, consisting of both physically visible and non-expressed alleles, is called its genotype.
