In a tournament Krillin had to fight Bacterian, a very stinky and unwashed man. At first Krillin couldn't fight because of the odor but Goku reminded him of the lack of his nose, so Krillin only imagined the odor and therefore defeated Bacterian.

On the other hand, like slapchoppin, I remember blood coming out of his non-existant nose when Goku flashed Bulmas tits one time...

krillin has no nose, you would know this if you actually watched dragonball

it was used as a joke....krillin has a nose he was being a smartass because he was tolerant of smells

pretty sure he had blood coming out of where his nose should be one time

that may have happened, but it is a confirmed fact, ill try to find a youtube video about it. But during the world tournament krillin had to find a huge smelly dude that could knock anyone out with his smell. Krillin said to goku something along the lines of "Goku its fine, I have no nose so i cant smell him" then krillin kicked the dudes ass.

Well they were stated by official sources (very official), so I'm not making this stuff up

im not saying you are making them up but many arent facts, most are just like "well look at this"

but if it was a recessive trait than it couldn't be shown in a child unless both parents were carriers of the gene

But then again Goku isn't human, so it probably wound't work that way

Well his genes would need to be very similar to a human's to be able to be able to produce viable offspring with one, and either way recessive by definition means that it would only show up if a recessive copy was received from both parents, otherwise it would be dominant.
