How are alleles different from genes?

Answer 1

A gene is a section of DNA that codes for a specific protein. An allele is the different forms of that gene.

The commonly used examples are things such as eye colour (although this is an over simplification as the true nature of the genes governing eye colour are a little more complex):

You have a GENE for eye colour.

That GENE comes in (normally) two forms.

These two forms are called ALLELES.

One ALLELE is for blue eyes and one ALLELE is for brown eyes.

ALLELES can be DOMINANT, RECESSIVE or CO-DOMINANT.

Answer 2

A gene is a segment of DNA that codes for a functional product (protein). This influences an organism's traits.

An allele is a form of a gene. For example, the alleles for ABO blood type are A, B and O.

Answer 3

Genes make up a larger category of which alleles are a part. For example, you have a gene for hair color, but and allele for brown hair or red hair. A gene defines the general characteristic you are looking at (hair color, eye color, etc. ) while the allele give you the specific trait.

Answer 4

Genes are segments of DNA that code for specific traits, while alleles are different versions of a gene that can result in variations of that trait. Genes can have multiple alleles, each inherited from one parent, and contribute to an individual's unique genetic makeup.

Answer 5

An allele is a way of identifying the two members of a gene pair which produce opposite contrasting phenotypes.

Answer 6

Gene is a smallest part of chromosomes which control a specific character or trait...... While allele is a alternate part of a gene....

Answer 7

Genes carry the information for a particular trait, such as hair. An allele is a variation of the gene that determines color, or thickness, or curliness of that hair.
