alelo

Alelo is the term used in genetics to denote a variant form of a gene located at a specific position, or locus, on a chromosome. An individual typically carries two alleles for each gene, one inherited from each parent, and the combination (genotype) influences the phenotype under different dominance relationships. Alleles can be dominant, recessive, co-dominant, or show incomplete dominance. Many traits are influenced by multiple genes and environmental factors, but single-gene examples are commonly used for explanation. Alleles arise by mutation and can be maintained in populations at characteristic frequencies.

In population genetics, allele frequency describes how common an allele is within a population. The Hardy-Weinberg principle provides a null model for interpreting allele and genotype frequencies under conditions of large population size, random mating, and no evolutionary forces. Deviations from the model suggest the action of natural selection, genetic drift, mutation, or gene flow. Mutations introduce new alleles, while evolutionary processes can increase or decrease the prevalence of existing alleles over time.

Alelo is also the name of a Brazilian company that provides employee benefits solutions. Its offerings include digital platforms and prepaid or reloadable cards for meal allowances (vale refeição) and food/meal supplementation (vale alimentação), transportation benefits, and other rewards for workers. The service is aimed at employers seeking to distribute benefits to employees efficiently, with supporting tools for administration and merchant acceptance across networks.
