Barring genetics 101
pure bred (both parents are barred) males get a copy of the barring gene from each parent. Pure bred females only get a copy from the father. Females do not pass on barring to female offspring. Males pass on barring to each gender offspring. A barred rock is at the base a black bird, with the "bars" of white on the feathers. Since the males get two copies of the barring gene, they have more white than black. Females are darker overall, they have more black than white as they only get one copy of the barring gene.
That said, your boy looks like a pure bred barred bird. As stated above, sex links (non-barred rooster over barred hen) are overall darker colored---often confused with pure bred hens until combs, etc tell the story---and have red leakage on hackle feathers. Your guy is lighter colored, no leakage seen. I'm pretty confident saying your bird has two copies of the barring gene and all his offspring will be barred to some degree.
What colors are you going to get? I really don't know. The black as the base color seems to override a lot of other colors in my own backyard flock. I've had a pure barred rooster and a sex link rooster and have gotten some interesting mixes of birds, but lots and lots of black and white. I think the tetra tints might have dominant white, so you could get maybe some white birds with "ghost" barring, the sex links could maybe give you some red or calico barred birds (pretty!), and the Easter eggers are always a wild card! That's why I love breeding them!
