- Fingernail length
The trait of fingernail length is acquired and not inherited.
To determine which of the given traits is acquired, we need to understand whether they are influenced by genetics or external factors. Here's how we can approach each trait:
1. Eye Shape: Eye shape is primarily determined by genetics and is inherited from our parents. Therefore, it is not an acquired trait.
2. Number and Presence of Dimples: The presence and number of dimples on the face are genetic traits that are inherited. So, dimples are not acquired.
3. Fingernail Length: The length of our fingernails can vary based on certain factors such as personal grooming habits, nail care, and lifestyle choices. Since these factors are primarily influenced by external factors and personal choices, fingernail length can be considered an acquired trait.
4. Skin Tone: Skin tone is primarily determined by genetics and is influenced by the amount of melanin in our skin. While external factors such as sun exposure can temporarily darken or lighten the skin, the baseline skin tone is inherited and not acquired.
Based on this analysis, the trait that is acquired (not inherited) from the given options is Fingernail Length.
