Yes even if the spider does not prove out to be het when bred to an albino female his offspring will all be 100% het albino because they would get the gene from the mother. Also don't rule him out as not being het for albino from the first clutch as sometimes luck is not on our side and you could strike out a few times and then prove out for you. Then again he could prove out and you could get all albino spiders you just never now since the numbers on the punnet square are not a for sure thing. I know a breeder that struck out on the ivory in 7 clutches last season from a proven ivory producing line.
