One major internal environmental influence that affects gene expression is gender, as is the case with sex-influenced and sex-limited traits. Similarly, drugs, chemicals, temperature, and light are among the external environmental factors that can determine which genes are turned on and off, thereby influencing the way an organism develops and functions.
First we must appreciate that genes do not act in isolation. The genome in which a genotype is found can affect the expression of that genotype, and the environment can affect the phenotype.Not all pairs of alleles will have the same phenotype: dominance when AA = Aa in phenotype, A is dominant, a is recessive.irst we must appreciate that genes do not act in isolation.
