A) Of the following traits, eye color is inherited.
A) Of the following traits, which one is acquired (i.e., not inherited)? (1 point)
- Fingernail length
Fingernail length is an acquired trait, meaning it is not determined by genetics but can be influenced by factors such as grooming habits, diet, and overall health.

- Eye color
Eye color is an inherited trait, meaning it is determined by genetics and passed down from parents to offspring. It is controlled by multiple genes and can vary in different individuals and populations.
To determine which of the given traits are acquired (not inherited) and which are inherited, we need to understand the basic concepts of inheritance and acquisition of traits.
Acquired Traits: Acquired traits are characteristics that an organism develops during its lifetime as a result of environmental factors or personal experiences. These traits cannot be passed on to the next generation.
Inherited Traits: Inherited traits are characteristics that an organism inherits from its parents through their genetic material (DNA). These traits are passed down from one generation to the next.
Now, let's analyze the given traits to identify which ones are acquired and which ones are inherited:
A) Of the following traits, which one is acquired (i.e., not inherited)? (1 point)
1. Eye shape: Eye shape is an inherited trait. It is determined by the genetic makeup of an individual and is passed down from parents to offspring. Therefore, eye shape is not acquired but inherited.
2. Fingernail length: Fingernail length is an acquired trait. It can be affected by various factors such as personal grooming habits, nail care routines, and external conditions. Fingernail length is not determined by genetics, so it is acquired and can vary throughout an individual's lifetime.
3. Skin tone: Skin tone is an inherited trait. It is influenced by the genetic variation within a population. Different genetic factors contribute to variations in skin pigmentation, resulting in various skin tones among individuals. Therefore, skin tone is not acquired but inherited.
4. Number and presence of dimples: The number and presence of dimples are inherited traits. Dimples are caused by specific facial muscle variations and are determined by genetic factors inherited from parents. Therefore, the number and presence of dimples are not acquired but inherited.
In summary, among the given traits, fingernail length is the only trait that is acquired (not inherited). Eye shape, skin tone, and the number and presence of dimples are all inherited traits.
A) Of the following traits, which one is inherited? (1 point)
1. Eye color: Eye color is an inherited trait. It is determined by the combination of genes inherited from parents. Different genetic variations contribute to variations in eye color among individuals. Therefore, eye color is an inherited trait.
2. Reading: Reading is a learned skill and not an inherited trait. It is acquired through education and practice.
3. Writing: Writing is also a learned skill and not an inherited trait. It is acquired through education and practice.
4. Riding a bike: Riding a bike is a learned skill and not an inherited trait. It is acquired through practice and motor skill development.
In summary, among the given traits, eye color is the only trait that is inherited. Reading, writing, and riding a bike are not inherited traits but skills that are acquired through learning and practice.
