homologs
Structurally similar relatives
Homologs are things that share a common origin or structure.
In biology, homologous chromosomes are paired chromosomes with matching genes—one from each parent.
Homologous structures in different species share evolutionary ancestry: a bat's wing and a human arm are homologs.
In chemistry, homologs are compounds differing by a repeating unit, like successive members of a series.
The adjective is homologous.
