PATHOLOGY

Detailed explanation-1: -Genotype generally remains constant from one environment to another, although occasional spontaneous mutations may occur which cause it to change. However, when the same genotype is subjected to different environments, it can produce a wide range of phenotypes.

Detailed explanation-2: -DNA determines a person’s height. However, environmental factors, such as nutrition and exercise, can affect growth during development. As children get older, they need good nutrition and plenty of exercise to help their bodies make the hormones they need to grow.

Detailed explanation-3: -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-4: -Food, temperature, sunlight, and water are examples of environmental factors that can affect an organism’s traits. Many characteristics of plants and animals involve both inheritance and the environment.
