the meaning of ” an allele is a specific form of gene”
In: 4
So genes are sections of DNA that determine specific traits that can be inherited, such as the color of your eyes or how tall you are.
Alleles are simply different versions of these genes. For instance, for the gene that determines eye color, one allele might give you blue eyes, while a different allele might give you brown eyes.
So when we say “an allele is a specific form of a gene,” we mean it is a particular version of a gene that dictates a specific outcome for a trait. It’s kind of like how a light switch can be in one of two forms: on or off. Alleles are the different “settings” that a gene can have, which then determine the specific characteristics an organism displays.
Imagine filling out a form. The form has spaces where they request that you fill out your name, your age, your height, your eye color, and so on.
A gene is a specific section of DNA that codes for a specific piece of data; it’s like the different blanks on the form.
Alleles are particular alternate forms of the gene; they’re like the value that you’d actually write into the blank, such as “brown” or “blue” or “grey” or “hazel”.
So if the gene named *rbprotein* is responsible for a protein found in the membranes of red blood cells, the alleles are the different sequences coding for the various proteins that could potentially be there. If a person has protein A, they have the A allele; protein B, the B allele; AB, they have copies of both alternate values of that gene.
its basically a different variant of the same protein, proteins are amino acids bonded together in chains, an allele of a protein is basically the protein where some of the amino acids may be different but the overall sequence is very similar (so it essesntially performs the same function although maybe a little differently)
If a gene is a place that you can write a letter, an allele is what letter is written there.
