I had a theory pretty similar so I get where you're coming from

The kirishima siblings ukaku is unuasually flexible and can be used for offence/defense etc so its possible they were influenced by their dad

I think that certain kagune types are ressesive and others are domanant, if two are dominant then    either the ghoul will have a dual type or the kagune they have will be influenced by the one they didnt inherit.

since both kirishima's had an ukaku we can assume that the ukaku was the dominnt gene, making the koukaku ressesive (this tyes in with the tsukiyama families inbreeding-maybe they wanted to keep their kagune type pure?)

Ryouko fueguchi's parents must have both had a koukaku parent, grandparent etc or been a koukaku, they were carriers and so when they had a kid they're child had a different kagune than either of them (i dunno which side of the family she inherited from tho). the same goes for Matsumae who'e parents were rinkaku who carried the koukaku gene

Miza's kakgune tells us that Bikaku is the dominant gene over rinkaku (which fits in with matsumaes thing, if only one parent had the rinkaku gene) and thus over koukaku, meaning both tsukiyama's parents had to have the koukaku gene for it to trump the bikaku

if rinkaku is ressesive then that teis in with this theory

so to summerise

ukaku/bikaku trumps koukaku and rinkau unless both parents are of koukaku/ rinkakuancestry in which case it's 50/50

if a ghoul had koukaku/ rinkaku parents or ukaku/bikaku parents the chances are 50/50 (possibley the chance of a dual kagune is much higher)

if this doesnt make sense i can try to explain it better
