Artificial selection or selective breeding can be defined as the induced breeding process in which humans select parents of plants and animals that have desired traits that are beneficial for them to produce offspring that have characteristics of both parents and they are of improved yield and quality. This brings the change in the phenotypes of the offspring as compared to the parents. As the passage of dominant desirable traits in the genotype from either of the parent when gets expressed then the phenotype of the organism also change.
The pH of an amino acid is determined by the nature of the side chains of that amino acid. If the side chain of an amino acid contains amine functional group the amino acid will be basic. The acidic amino acids are acidic because they have carboxylic acid functional groups at their side chain.
