orthologous genes

orthologous genes

[ôrthol′əgəs]
genes in different species that are similar in their nucleotide sequences, suggesting that they originated from a common ancestral gene.

orthologous genes

any genes found in different species that, while nonidentical, can be traced back to a common ancestor.
