Genetic polymorphism. Edit 0 2 â¦. A genetic polymorphism is the existence of two or more variants-which may be allelic, phenotypic, chromosomal or general DNA sequence variants-at significant frequencies in a population. A frequency of 1% or more is generally considered to be a polymorphism.Types of polymorphism include:enetic polymorphism. Edit 0 2 â¦.

Failure to consider the statistical nature of material chemical compositions andprocesses can lead towriting unrealistic heattreating specifications. To achieve consistent results that meet the specification after heattreatment, the specification must includetolerances that are achievable on acommercial basis.
Chemical energy is stored inside a substance or object until it is involved in a chemical reaction. Our bodies use chemical energy to perform daily functions. During an exothermic chemical reaction, chemical energy in the form of heat is released.Plants perform a chemical reaction each time they use sunlight to make their own food during photosynthesis.ur bodies use chemical energy to perform daily functions.
