Out of the following traits, the one that is acquired (not inherited) is "skin tone."
To determine which trait is acquired and not inherited, we need to understand the difference between the terms.
Inherited traits are characteristics that are passed down from parents to offspring through genes. They are determined by a combination of genetic factors, such as DNA. These traits are generally not influenced by environmental factors.
Acquired traits, on the other hand, are characteristics that are developed or acquired throughout an individual's life. They can be influenced by various factors, including environmental conditions, lifestyle choices, and personal experiences.
Now let's examine the traits mentioned:
1. Eye shape: Eye shape is primarily an inherited trait. It is determined by a combination of genes from both parents and is generally consistent within a family. Therefore, eye shape is not acquired but inherited.
2. Fingernail length: Fingernail length is an acquired trait. It can change throughout a person's life due to factors such as nail care habits, lifestyle, and certain medical conditions. A person can choose to trim or grow their fingernails, which makes it an acquired trait.
3. Skin tone: Skin tone is primarily an inherited trait. It is determined by the amount of melanin present in the skin, which is determined by a combination of genetic factors. While sun exposure or certain medical conditions can temporarily affect the appearance of skin tone, the underlying tone itself is inherited.
4. Number and presence of dimples: The number and presence of dimples can vary among individuals and are primarily an inherited trait. They are caused by the structure of facial muscles and connective tissue, which is determined by genetics rather than acquired.
In conclusion, out of the mentioned traits, fingernail length is the acquired trait.
