Amino acids selective pressure [ edit ] It has been shown that putting an amino acid bio-synthesizing gene like HIS4 gene under amino acid selective pressure in yeast causes enhancement of expression of adjacent genes which is due to the transcriptional. Here the giraffe neck is the best example. For example, if a farmer treats a cornfield with a rate of soil insecticide that is lethal to some population members but not to others, they are applying selection pressure. Application and measurement type. Sexual Selection. . . Selection Pressure: The external forces that are essentially imposed on a population to either increase or decrease the occurrence of a trait are called selection pressure. The selection pressures on males and females to obtain matings is known as sexual selection; it can result in the development of secondary sexual characteristics that do not benefit the individual’s likelihood of survival but help to maximize its. As a result, the trait distribution of the population is shifted towards the other extreme of that specific trait. Sexually reproducing species must find mates, and sexually selected traits reduce survival. In theory, at intermediate levels of immunity, there is enough viral replication to generate escape variants and enough selection pressure to amplify those variants so that they grow to high. .
