Homologs- when two different genes are related by the same ancestral DNA sequence.
The homologs in the examples are all of them , as they arise from the same ancestral gene.
Orthologs- genes in different species that arise from the coomon ancestral gene by speciation.
examples - Y alpha- Z beta1, Y alpha- Z beta2, Y alpha- Z alpha, Y alpha- Y beta
Paralogs-two genes are paralogs if their last common ancestor is a duplication event.
so the examples here will be Y beta- Z beta1, Y beta- Z beta 2
