AG Pumpkin vs Squash Genetics

Differences between pumpkin and Squash.
Known or suspected genes controlling these differences.

Atlantic Giant pumpkins are some color of orange. One often reads that someone's giant fruit was ruled a squash. What are the small differences which cause ruling to be required.? How genes are different between squash and pumpkin?

Typical Traits of Mature AG Pumpkins

The main difference is color. To be accepted as a pumpkin in contests, the fruit must be some color of orange.

Other traits of pumpkins are ribs, ---,

The red allele is very rare in C. pepo (ordinary pumpkins). Has there ever been a red Atlantic Giant? The red allele in C. pepo has been described.

Typical Traits of Mature Giant Squash (C. maxima)

Often green or partly greeen; what about white?

Often has stripes.

Traits Visible in the Young Fruit

The color of the mature fruit is already hinted before the female flower is pollinated. If green it will be squash; if yellow it may be a pumpkin (I am not sure about this)
