How would you know if the cause of variation is genetic or environmental?

The main difference between genetic variation and environmental variation is that genetic variation is the variation of the genotype between two individuals within the same species whereas environmental variation is the dependence of the phenotype upon the environmental factors.

How would you know if the cause of variation is environmental?

Environmental causes of variation

Characteristics of animal and plant species can be affected by factors such as climate, diet, accidents, culture and lifestyle. For example, if you eat too much food you will gain weight, and if you eat too little you will lose weight.

What is the difference between environmental and genetic variation?

The key difference between genetic variation and environmental variation is that genetic variation mainly affects the genotype though it also affects the phenotype, but environmental variation mainly affects the phenotype.

How do you determine genetic variation?

Genetic variation can also be identified by examining variation at the level of enzymes using the process of protein electrophoresis. Polymorphic genes have more than one allele at each locus.

What is the main difference between genetic and environmental factors?

Your genes hold the basic instructions for your body to grow and function, but they are far from the only thing controlling your traits. Most traits are shaped both by a person’s genes and by environmental factors. Environmental factors include everything outside of DNA that affects your traits.

What characteristics are inherited and environmental?

What is the difference between environmental and inherited traits? Inherited traits are the traits you get from your parents through the genes they pass down to you, their offspring. Environmental traits are influenced by your environment. You can learn them or control them.

What are examples of genetic variation?

Genetic variation results in different forms, or alleles?, of genes. For example, if we look at eye colour, people with blue eyes have one allele of the gene for eye colour, whereas people with brown eyes will have a different allele of the gene.

What is environmental variation in biology?

The differences in characteristics between individuals of the same species is called variation . … Some variation is the result of differences in the surroundings, or what an individual does. This is called environmental variation.

How can the environment affect an organism’s traits give an example?

Differences in environmental factors can cause organisms that are related to end up looking or behaving differently. … Food, temperature, sunlight, and water are examples of environmental factors that can affect an organism’s traits. Many characteristics of plants and animals involve both inheritance and the environment.

What is inherited genetic variation?

Inherited (or hereditary) variants are passed from parent to child and are present throughout a person’s life in virtually every cell in the body. These variants are also called germline variants because they are present in the parent’s egg or sperm cells, which are also called germ cells.

What does environmental or genetic mean?

= Gene environment interaction is an influence on the expression of a trait that results from the interplay between genes and the environment. Some traits are strongly influenced by genes, while other traits are strongly influenced by the environment.
