what is an allele and what is the difference between an allele and a gene?
An allele is a variant form of a gene that can result in different traits or characteristics in an organism. Alleles are found at the same location on a chromosome and can be dominant or recessive.
The main difference between an allele and a gene is that a gene is a specific sequence of DNA that determines a particular trait, while an allele is a specific form of that gene that can result in variations in that trait. In other words, genes are the broader genetic instructions that determine a trait, while alleles are specific versions of those genes that can result in different expressions of that trait.
