An allele is a variant form of a gene, not a trait. Each individual inherits two alleles for each gene, one from each parent. Alleles can influence the traits by determining how certain genes will express themselves, but they are not traits in themselves.

Questions and answers

  1. What is an allele in genetics?

    An allele is a variant form of a gene that can influence how traits are expressed in an organism.

  2. How do alleles differ from genes?

    Genes are segments of DNA that code for traits, while alleles are different versions of the same gene.

  3. Can an allele be considered a trait?

    No, alleles are not traits themselves but determine how traits can be expressed.
