Runner mating with non-runners?

[BlessedChaosHomestead]

Forgive the ignorance and what not.
Still new to the poultry/waterfowl world especially with the mating area.

We have a male runner duck.

We have 2 female runner ducks. (One is almost 12wks, the other laying.)
Then we have a hodge podge of different breeds of ducks. Swedish Blue & Black, Cayuga, Campbells, Rouen and Mallard.
Will there be a problem with our male runner x swedish blue? or mallard? etc...

What genetics will come through? Runner? Or regular??

Thanks in advance for the help!

All domestic ducks,except Muscovy, are from Mallards and can interbreed. The runner pattern is a dominant trait so assuming that he is a fawn and white runner, his offspring will have white splotches on them. You could get some interesting babies. Here is a link to an article from Pyxis about duck genetics: https://www.backyardchickens.com/articles/mallard-derived-duck-color-genetics-basics.74277/

Thanks!
Ugh I don’t want fawn and white. Lol but that’s what he is.
His hatched offspring test baby is a fawn. Mom was full chocolate until almost a year then she became chocolate pied.
