Here's a breakdown:
* Gene: A segment of DNA that contains the instructions for building a specific protein.
* Allele: A specific variation of a gene. Since we inherit one chromosome from each parent, we have two copies of each gene, and these copies may be the same or different alleles.
* Trait: A characteristic of an organism, like eye color or hair color, that is determined by genes.
Example:
* Gene: The gene for eye color
* Alleles: One allele might code for blue eyes, and another for brown eyes.
* Trait: The actual eye color of an individual (blue, brown, etc.)
So, the specific allele you inherit from each parent determines the trait you express. For example, if you inherit the brown eye allele from your mom and the blue eye allele from your dad, you will likely have brown eyes, as brown is usually dominant over blue.
