1. Of the following traits, which one is acquired (i.e., not inherited)? (1 point)

eye shape
fingernail length
skin tone
number and presence of dimples

2. Of the following traits, which one is inherited? (1 point)
eye color
reading
writing
riding a bike

1. Skin tone is acquired and not inherited.

2. Eye color is inherited.

1. Of the following traits, the one that is acquired (not inherited) is: fingernail length. Eye shape, skin tone, and the number and presence of dimples are all traits that are inherited from our parents.

2. Of the following traits, the one that is inherited is: eye color. Eye color is determined by genetic factors passed down from our parents. Reading, writing, and riding a bike are skills that are learned and not directly influenced by genetic inheritance.

To determine which trait is acquired (not inherited) in question 1, we need to understand the meaning of the terms.

1. Eye shape: This trait is primarily determined by genetics and is inherited from our parents. Different eye shapes, such as almond-shaped or round, are a result of genetic factors.

2. Fingernail length: Fingernail length can vary among individuals, but it is primarily determined by genetic factors. However, the growth and maintenance of nails can be influenced by factors such as nutrition, hygiene, and overall health. Therefore, while fingernail length can be influenced by acquired factors, the trait itself is mostly inherited.

3. Skin tone: Skin tone is primarily determined by genetics and is inherited from our parents. Different amounts of melanin, a pigment responsible for skin color, are determined by genetic variations.

4. Number and presence of dimples: Dimples are a genetic trait and are inherited. Some people have dimples on their cheeks, while others do not. The presence or absence of dimples is determined by genetic factors.

Based on this information, the trait that is acquired (not inherited) is reading in question 2. While the ability to learn and read is influenced by a combination of genetic, environmental, and educational factors, it is primarily acquired through education and practice, rather than directly inherited through genetics.

In summary:
1. The trait acquired (not inherited) is reading.
2. The traits inherited are eye color, riding a bike (to a certain extent), and writing.
