Human variation refers to the differences in physical and genetic traits among individuals and populations within the human species. These variations can encompass a wide range of characteristics, including skin color, height, facial features, and susceptibility to certain diseases. Factors such as genetics, environment, and culture contribute to this diversity, highlighting the adaptability and complexity of humans as a species. Understanding human variation is essential for fields like anthropology, medicine, and genetics.
Natural eye colour is discontinuous. :) !
Artificial selection.
'Environmental variation' refers to the differences in environmental conditions such as temperature, humidity, or nutrient availability within a specific ecosystem or location. This variation can have significant impacts on the growth, behavior, and reproduction of organisms in that environment. Factors contributing to environmental variation can include natural processes, human activities, and climate change.
It is used in the thermometers as it detects the heat change.It points out the variation of temperature of human body.
The pressure variation in a sound wave is amplified in the human ear through the mechanism of the middle ear. When sound waves hit the eardrum, they cause it to vibrate. These vibrations are then transferred through the bones of the middle ear, which act as a lever system to amplify the pressure variations before reaching the inner ear.
Human species, as in the variation in height.
Human recombination is a significant source of genetic variation.
It is an example of continuous variations.
This is a typical kind of continuous variation which is controlled by polygenes.

The variation in human hair color is determined by genetics, specifically the combination of different genes that control the production of melanin, the pigment that gives hair its color. Other factors such as age, hormones, and environmental influences can also play a role in hair color variation.
Which would most likely decrease the genetic variation in the human population?
