I was juicing my Whittakers' gold grapefruit tonight and found this one:
They must have been a sport of white grapefruit!

Very Interesting? What does the gold fruit the taste like?

Wow-that is neat-I have never seen a grapefruit like that.

Could you explain a "sport" and comment on whether you think the seeds on the white side would have different genetics than those on the colored side? Thanks, Barbara

First time I've seen a grapefruit that is orange flesh colored. Most I've seen are pigmented towards the pink or red, and also the whites and yellow to yellow green. I would have mistaken it as an orange, except for the one with the striped flesh.

Barb, a sport is a modified genetic version of a plant that may or may not be expressed at any particular time. Once to modification occurs, it may or may not be expressed (visible), but both versions are often retained in the genetic code. A good example is in African Violets, where some bi-colored flowered varieties will switch back and forth between the solid and bi-colored versions, especially when they are propagated.

That's really interesting. Did the two different colors have different tastes?

We have to get Mr Texas to tell us that. I noticed something else interesting-- seeds near the outer edge--I don't think I have ever seen that before -- is that normal?

Skeet, so the seeds on both the white and orange segments will more likely than not have the same chances at carrying on the genetic anomaly?

If the tree produced a branch with several fruit like this, and the balance of the tree did not, would it be a similar situation to a tree producing a variegated tree branch? Thanks, Barbara

The taste is very mild with little to any grapefruit bitterness, the grapefruit for those who don't like grapefruit. I juiced all the fruit so didn't taste any white flesh.

Skeet I think the seeds are there from cutting it open, I don't think the fruit produced seed on the outer edge.
