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.
This is a chemical property. Metals in general have they chemical property of reacting with an acid. Zinc reacts with hydrochloric acid to produce hydrogen gas. This is a chemical property. Chemical change results in one or more substances of entirely different composition from the original substances. The elements and/or compounds at the start of the reaction are rearranged into new product compounds or elements. A CHEMICAL CHANGE alters the composition of the original matter.
