In each case, the F1 will appear different than either parent. Using the pink as female in the first case would result in a more obvious difference, while using the orange as the parent in the second case would be more obvious.

Darren,
This is a great article, easy to understand for the layperson thank you for posting it.
I am interested in the opaque red high lycopene skin trait. A clear epidermis pink skinned yellow cherry appeared in a potato leaf F2 selection of one of my crosses. Marsha is growing out the F3 and the coloration has come through in the F3 as well. It looks like the photo in the article except once ripe the skin on our tomato is a bright dark apricot pink.
I initially thought it was a bicolour as the color begins as s blush on the blossom end but does not extend into the interior. The blush continues to develop until the whole exterior becomes pink.
Would you look at the KARMA project thread and tell me if you think this is the explanation for the color of this cherry.
Thank you
