Prep 7 - Coursework ExampleThe environment has a operose influence when it comes to gene expression. For example, the mixture of genes he inherits and the environment, he interacts with determines the personality of an individual. Various environmental cues can alter the gene expression. They be the extracellular and intracellular concentrations of contrasting ions (Dawkins, 1999).Reaction norms could be used to understand phenotype plasticity in the below manner. Phenotype plasticity shows the degree to which the phenotype of an organism is. The response patterns display the relationship between the genotype and phenotype (Dawkins, 1999).The variability could be structural variations and copy number variations. The difference between broad sense and narrow sense heritability is that the general sense shows the genetic contributions to the phenotype form of a population and the strict sense does not reflect genetic contributions. Heritability is measured by coming up with the re lative contributions of non-genetic and genetic differences to the total phenotypical variation in a population (Dawkins, 1999).The narrow sense heritability and the strength of selection work together in a manner that their response is since they are necessary for selecting (Dawkins,
