The variations in height and eye colour can be caused by both genetics and the environment.

1. Height: It is influenced by a combination of genetics and environmental factors. While a person's genetic code can predispose them to a certain height range, environmental factors such as nutrition and health can also play a significant role in determining how tall a person grows.

2. Eye Colour: This is primarily determined by genetics. The colour of your eyes is dictated by the amount and type of pigments in your eye's iris, as well as how the iris scatters light. However, the environment can also influence eye colour to some extent. For example, sunlight can affect the intensity of your eye colour, and certain diseases or medications can change eye colour as well.

On the other hand, ear piercing and blood group are not influenced by genetics or the environment.

1. Ear Piercing: This is a physical modification that has nothing to do with genetics or the environment. It is a personal choice and is usually done for cultural, religious, or personal reasons.

2. Blood Group: Your blood type is determined entirely by the genes you inherit from your parents and it cannot be changed by environmental factors.
