|
Eye colour
|
|
|
Blood type
|
|
|
Skin colour

All of the above

Explanation:
Detailed explanation-1: -Eye colour, skin tone and face shape are all determined by our genes so any variation that occurs will be due to the genes inherited? from our parents.
Detailed explanation-2: -Examples of genetic variation in humans include blood group, skin colour and natural eye colour. Whether you have lobed or lobeless ears is due to genetic causes. Biological sex is also an inherited variation-whether you are male or female is a result of genes you inherited from your parents.
Detailed explanation-3: -Only variation that arises in germ cells can be inherited from one individual to another and so affect population dynamics, and ultimately evolution. Mutations and recombination are major sources of variation.
