👉 In biology, an orthologue is a type of genealogical relationship where one organism carries genes from another organism. This means that two organisms have the same set of genes, but the sequence and function of these genes are different between them. For example, humans and chimpanzees share many genes in their genomes, but they differ in terms of how they use those genes for survival. The term "ortholog" is derived from the Latin word "orthologus," which means "like."
