Final answer:
Elisa's hair color is the physical feature most likely to change if she lived in a different location, due to environmental factors, such as exposure to sunlight.
Step-by-step explanation:
If Elisa lived in a different location, the physical feature that would most likely change is her hair color. Environmental factors such as sunlight can affect the pigmentation of hair over time. For example, prolonged exposure to sunlight can lighten hair color due to the breakdown of melanin, which determines the color of hair. In contrast, changes to her eye color, size, or masculine appearance are primarily determined by genetics and are not typically influenced significantly by the environment.
Considering information about physical traits, if a certain trait is related to genetic mutations, like those caused by Hox gene mutations, it could result in phenotypes such as abnormal body length or height or having a different number of appendages than normal. However, these changes are linked to genetic factors rather than environmental ones like location.
