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.

Genes that come together with different alleles are called linked genes. These genes are located close together on the same chromosome and tend to be inherited together during meiosis.
An allele is a specific variant of a gene, which is a unit of hereditary information. Genes can have different alleles that produce variations in traits. Therefore, alleles exist within genes as different versions or forms of the same gene.
Genes that come together with different alleles are referred to as "heterozygous." In a heterozygous genotype, an individual has two different alleles for a particular gene, one inherited from each parent. This genetic variation can contribute to diverse traits and characteristics within a population.

Different types of genes are called alleles, which are alternate forms of the same gene that can produce variations in a trait. Additionally, there are also different categories of genes such as regulatory genes, structural genes, and non-coding genes that play various roles in controlling different biological processes.
Alleles are genes that exist in multiple forms.
Genes that come together with different alleles are called linked genes. These genes are located close together on the same chromosome and tend to be inherited together during meiosis.
Multiple alleles are genes that have more than two alleles. An example of this would be blood types, with ABO as three separate alleles.Polygenic traits are traits whose phenotype rely on alleles from different genes. An example of this would be hair type, which relies on genes from different parts of chromosomes.The main difference is that multiple alleles are genes with 3 or more alleles; polygenic traits do not necessarily have more alleles, but they rely on on multiple genes.
Genes can exist in different forms or variations called alleles. Alleles are alternative versions of a gene that can lead to different traits or characteristics in an organism. For example, a gene that controls eye color may have alleles for blue, brown, or green eyes.
Genes can exist in different forms called alleles, which are variations of a gene. Alleles can be dominant or recessive, influencing the expression of traits in an organism. Additionally, genes can undergo mutations, such as insertions, deletions, or substitutions, leading to genetic diversity within a population.
