Herein, how does the environment affect gene expression?
Internal and external environmental factors, like gender and temperature, influence gene expression. 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.
Furthermore, what characteristics of an organism affect gene function? The first known example pf sex-linked inheritance was discovered in pea plants. What characteristics of an organism can affect gene function? The genetic makeup of an organism at fertilization determines only the organism's potential to develop and function.
Also know, how does the environment affect the phenotype of an organism?
Environment Can Impact Phenotype Environmental factors such as diet, temperature, oxygen levels, humidity, light cycles, and the presence of mutagens can all impact which of an animal's genes are expressed, which ultimately affects the animal's phenotype.
Why do organisms regulate their gene expression?
Genes are expressed when they are transcribed into mRNA and translated into protein. Gene expression is carefully regulated by all organisms so that the correct amount of each protein is made. Eukaryotic organisms regulate their gene expression differently than prokaryotes.
