The Patternless was revealed 1991 and was the first recessive Leopard Gecko mutation to be discovered. It was originally misidentified and coined as a Leucistic mutation but was later renamed the Patternless in 1995 shortly after the Blizzard (Leucistic) was discovered.  Babies emerge with light yellow body color and dark spotted pattern, which is particularly concentrated in the head and shoulder area. As they mature the pattern completely fades out and as adults they exhibit a completely patternless head, body and tail. Color ranges from light yellow to gray with some even displaying a greenish tone while the tails have a purple-gray tone. Although simple in overall appearance they are a beautiful morph.
