As for tiger trout - my son recently caught a pin fish (meriting a state award) that really excited him - Ted calls them "Frankenstein fish." He perceives them and other man-made genetic cocktails as insults to our biota (he loves brookies, browns and rainbows, fights for their survival and strongly feels there should be no reason to tamper with their natural perfection).Williams has no doubt that hybrids like tiger trout, splake, wipers, saugey and tiger muskies grow bigger and faster in certain waters, and that triploid salmonids grow bigger and faster, too.

The process of producing all-female triploid trout is not quite the same as genetic engineering or genetic modification.

Finally, to test the proof of principle that the QEXT assay is a specific method for measuring allele-expression ratios in clinical samples, we tested the optimized and validated QEXT assay in the trisomy 21 model system by evaluating all of the clinically important (i.e., informative) combinations: diploid heterozygous (AC) and triploid heterozygous (AAC or ACC) samples.
