is it biologically possible for a creature that can be compatible to reproduce with any creature?

just as the title, my question is can it possible for a creature that can reproduce with any/all creature despite it was different species/family? (not the alien xenomorph or parasite one/way but real interspecies reproduction activity) either as the one that do it or the one that giving birth/lay eggs.

the children can be mix of the parents gene, think like half-human, half-elf, half-dwarf, half-orc, etc. usually this is from human interacial/species (just an example) but the creature not necessary to be human or inteligent though.

what kind of genetic or reproduction organs to achieve it? (not restrict to only have single reproductive organ) outside of they are from the same universal anchestry/genetic handwave.

and will the half breed gonna be infertile or fertile? what kind of side effect to their genes?
