Orthologs are referred to those genes which are present in different species and these genes are originated from the common ancestral gene. This evolution happens due to the phenomenon of speciation and the gene remains functionally the same during the whole course of time.
In other words, the orthologs can also be stated as the homologs of genes that exist in different species but have the ability to catalyze the same reaction and hence the same proteins are expressed resultantly. In the genomes which are newly sequenced, it becomes difficult to identify the orthologs.
