# Super Highway

_Permalink: https://geckinspect.com/MorphGuide/super-highway_

**Rarity:** Very rare  
**Inheritance:** Incomplete dominant  
**Category:** Pattern

**Definition.** Super Highway is the two-copy form of Highway; some breeders report nostril and health problems in these hatchlings, but that is not established.

Two copies of Highway. Health problems reported, not established; avoid Highway x Highway.

Pairing two Highways gives about 25% Super Highway. Some breeders report nostril and health problems in Super Highway hatchlings similar to Super Cappuccino's, and those reports are the main reason Highway is placed, provisionally, on the Cappuccino and Sable gene. Neither the health problems nor the placement is established in published breeding records, so Geck Inspect badges it Emerging and advises against Highway x Highway until more is known.

**Key features:**
- Two copies of Highway
- Health problems reported, not established
- About 25% of babies from Highway x Highway

**How to identify it:**
- Needs two Highway parents
- Check nostril openings at hatch

**Lookalikes and how to tell them apart:**
- Highway (https://geckinspect.com/MorphGuide/highway): One copy also gives a clean stripe; telling one copy from two by eye is unreliable.
- Super Cappuccino (https://geckinspect.com/MorphGuide/super-cappuccino): Super Cappuccino's health problems are documented; Super Highway's are only reported.

**Notes.** Pair Highway to a normal (about 50% Highway), or to a Cappuccino or Sable for a compound with no super.
