What is environmental variation and examples?
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 some environmental variations?
For example, environmental variations in humans could be: Hair length – what length you choose to have your hair. Scars – caused by accidents personal to you. Muscle strength – dependent on how much exercise you do.
What is environmental variation in genetics?
Summary. Environmental variation (VE) in a quantitative trait – variation in phenotype that cannot be explained by genetic variation or identifiable genetic differences – can be regarded as being under some degree of genetic control.
How do you identify environmental variation?
Environmental variation can generally be identified if the variation disappears when both variant and normal plants are transplanted to a common environment. Therefore this is a test that should be performed [to aid in determining the cause of variation.]
What are some examples of environmental factors?
Environmental factors include temperature, food, pollutants, population density, sound, light, and parasites.
What are environmental characteristics?
Environmental characteristics include dependencies, competition and uncertainty. … It is suggested that the creation of appropriate climates and structural design as responses to environmental pressures may be considered as complementary strategies in an attempt to maintain administrative control.
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.
What are examples of variations?
For example, humans have different coloured eyes, and dogs have different length tails. This means that no two members of a species are identical. The differences between the individuals in a species is called variation.
What are variations explain with suitable example?
Answer : Variation can be defined as the differences among individuals within the same species which develops due to the mixing and assortment of genes of the parents that is passed onto the offspring’s. For example, we keep pets like dogs and cats.
How does the environment affect genetic variation?
These results suggest that ecological factors can have strong impacts on both population size per se and intrapopulation genetic variation even at a small scale. On a more general level, our data indicate that a patchy environment and low dispersal rate can result in fine-scale patterns of genetic diversity.
