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.
These changes of phase always occur with a change of heat. Heat, which is energy, either comes into the material during a change of phase or heat comes out of the material during this change. However, although the heat content of the material changes, the temperature does not.
