How do you identify if the cause of variation is genetic environmental or both?

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.

What is the difference between a genetic and an environmental 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.

What causes environmental variation?

Environmental causes of variation Characteristics of animal and plant species can be affected by factors such as climate, diet, accidents, culture and lifestyle. Another example is that of a plant that grows in the shade of a big tree – it will grow taller to reach more light.

Which type of variation is influenced by the environment?

Variation caused by the surroundings is called environmental variation .

What are inherited and environmental characteristics?

Some features vary because of a mixture of inherited causes and environmental causes. For example, identical twins inherit exactly the same features from their parents. Weight and height are common examples of characteristics that are influenced by both genetic and environmental factors.

What is environmental variation?

the ability of an organism to alter greatly its PHENOTYPE depending upon environmental conditions. The phenomenon is seen most clearly in plants, perhaps because they are fixed in the ground.

What are genetic variations caused by?

Mutations, the changes in the sequences of genes in DNA, are one source of genetic variation. Another source is gene flow, or the movement of genes between different groups of organisms. Finally, genetic variation can be a result of sexual reproduction, which leads to the creation of new combinations of genes.

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.

Which feature is due to environmental variation only?

Variation caused by the surroundings is called environmental variation . Here are some other examples of features that show environmental variation: flower colour in hydrangeas (these plants produce blue flowers in acidic soil and pink flowers in alkaline soil)

What are the main causes of genetic variation?

Genetic variation can be caused by mutations of genes, gene flow, random mating, random fertilization, and crossing over between homologous chromosomes. Random mating, random fertilization, and chromosomal crossing over lead to the reshuffling of alleles within a particular species. Mutations introduce new genes or alleles to the population.

What are the factors that cause variation in the environment?

Environmental Variation: Environmental variation is caused by the external environmental factors such as light, temperature, moisture, climate, exposure, minerals, diet, culture, and lifestyle.

What is variation in a species?

Variation is the differences between individuals within a species. This can be caused by inherited or environmental factors. Variation can be continuous or discontinuous. Inherited and environmental variation. Some variation within a species is inherited, and some variation is due to the environment.

What types of variation are difficult to identify easily?

However, biochemical and some behavioral variations (ex: knowledge, preferences, etc.) are difficult to identify easily. Genetic variation and environmental variation are both vital for natural selection and evolutionary changes.
