Answer:

Allele is the form in which sequenced information within a single gene can be expressed. One allele is paired with another within a gene, which is part of a chromosome and which determines the expression of specific traits.

Explanation:

The genetic information is contained in the DNA, and each molecule of this nucleic acid forms a chromosome containing genes, fragments of the DNA of the chromosome with a sequence of nucleotides for the synthesis of specific proteins.

Genes determine morphological or functional features of a living being. Each gene contains two alleles for each trait it determines, the alleles being different sequences of nucleotides that constitute different ways in which a trait can be expressed.

<h3>How are the alleles related to genes, chromosomes and traits? </h3>

Each gene contains two alleles, either the same or different, with the sequence of nitrogenous bases to determine the possible ways in which a trait is expressed. The different sequences of the alleles can produce specific modifications of the function of that gene, conditioning the different forms of expression of a trait.

Genes, which contain alleles, are found within a chromosome, at a specific location called a locus.
