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?

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 of the following are examples of environmental effects on 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.

Which is an example of environment affecting the phenotype of an organism quizlet?

An organism’s phenotype is a combination of genetic factors, environmental factors, and the interactions between them. For instance, environmental changes can lead to changes in the genotype of the organism: if the pH in the soil where hydrangeas grow is acidic, the hydrangeas will turn blue.

How does the environment influence gene expression quizlet?

Environmental factors can affect gene expression such as: the production of skin pigmentation during exposure to sunlight in humans. In embryonic development, the embryo contains an uneven distribution of chemicals called morphogens.

Which is an example of environmental influence on gene expression?

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.

What are some examples of environmental characteristics?

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.

How do genes affect phenotypic expression?

The genome in which a genotype is found can affect the expression of that genotype, and the environment can affect the phenotype. Genes can also be pleitropic when they affect more than one trait. The single base pair mutation that lead to sickle cell anemia is a classic example.

How do genes affect phenotype?

An organism’s phenotype is determined by its genotype, which is the set of genes the organism carries, as well as by environmental influences upon these genes. … Phenotypes also include observable characteristics that can be measured in the laboratory, such as levels of hormones or blood cells.

Which of the following are factors that likely influence phenotype?

Genetic and environmental factors combine to influence phenotype. Genetic and environmental factors combine to influence phenotype.

What determines or contributes to your phenotype quizlet?

your genotype is what makes your phenotype. your base sequence of a gene is what determines your allele- dominant or recessive, your two alleles determine ypur genotype, your genotype determines your phenotype. an organism’s genotype determines theor phenotype, because the genotype has the genes.

Which trait is determined by both genetics and the environment quizlet?

Diabetes is a discontinuous trait that is determined by both genetic and environmental factors.
