50% blue 50% black across the board.Blue to lav is not reccomended.Said to produce a very light color if 2 copies of lav and 1 copy of blue.Had a couple of these last year but mine were lav with the ink spots sometimes found in blue.Test matings confirmed their genes.I did this just to see what I would get.Lost the photos in a computer crash.Question was asked of me what you get when you mate blue to black and blue to lavender? My guess is blacks across the board, but I really don't know. Anyone have an idea?
