This means that each dominant allele "adds" to the expression of the next dominant allele. Usually, traits are polygenic when there is wide variation in the trait. For example, humans can be many different sizes. Height is a polygenic trait, controlled by at least three genes with six alleles.
Both the terms "living" and "biotic" describe an organism that holds life. However, an organisms stops "living" after it dies, but never stops being "biotic". This is because "biotic" means anything that has ever had life, whereas "living" only describes things currently alive.
As solar energy interacts with carbon dioxide, water vapor, and several other gases in the troposphere, it warms the troposphere process known as the Green house effect.
- Troposphere is the lower most part of the earth's atmosphere comprises of Nitrogen, Oxygen, Argon, Carbon dioxide and Water vapour.
- Carbondioxide, water vapour and other gases like methane are concentrated highly in the Trophosphere due to some human activities (Industrial revolution).
- Such excess Green house gases forms a shield layer which retains the heat by trapping the long wave radiation of solar energy in troposphere. As a result, global warming and abnormal weather conditions occurs in the planet.
