Answer:
Homologs,Orthologs, Paralogs
Explanation:
Homologs are referred to as gene that form the basic of Organization. They are homologous protein with genes coding for it.
They have the same ancestor and similar base sequence.
Orthologs are genes that arise from the divergence of a gene into two. i.e two genes arising from splitting of a gene having a common ancestor
Paralogs are genes form when a gene is dulplicated. This duplication of gene gives rise to a paralog.
