Detailed explanation-1: -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.
Detailed explanation-2: -Various factors, including genetic makeup, exposure to harmful substances, other environmental influences, and age, can affect expressivity. Both penetrance and expressivity can vary: People with the gene may or may not have the trait and, in people with the trait, how the trait is expressed can vary.
Detailed explanation-3: -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.
Detailed explanation-4: -Internal factors that affect gene expression include hormones, gender and metabolic activities. External factors include temperature, light and other chemicals which might be taken with food.
Detailed explanation-5: -In total, 2, 468 genes showed increasing expression intensities with temperature whereas for 2, 670 genes expression intensity decreased with increasing temperature.
