Just when you thought you knew everything about tomatoes.

https://pmc.ncbi.nlm.nih.gov/articles/PMC8968427/

It's a few paragraphs down.

Why does it matter? Well, it might not...

But it might.

This is the part that is worth reading:

"Endopolyploidy, the occurrence of different ploidy levels within an organism, is widespread among plant taxa. It is often generated by endoreduplication where the complete genome is replicated without mitosis (Scholes and Paige, 2015). In tomato, cells with different ploidy are found in all organs (Smulders et al., 1994). Developmental stages such as young/old organs and growth conditions affect the ratio of ploidy level in cells. Furthermore, genome multiplication is a frequent occurrence during crop domestication. Many of the most economically important crops are polyploid, including potato (Solanum tuberosum), wheat (Triticum aestivum), and cotton (Gossypium hirsutum). Polyploidy conveys advantages in terms of genomic buffering, viability, and environmental robustness."

Hybrids? Different chromosomes and genetic diversity. I'm wondering how Dan's crosses could improve diversity in tomatoes. 9.44 x Westerland for instance.?

I dont know if the polyploidy affects the inheritance of genes... it's possible they dont have to conform to standard mendelian inheritance.

I'll need to review the polyploidy aspects, although I took genetics in college. It's been about 50 yrs. ago. We had fruit flies in and studied different stages and hybrids, generations etc. etc. Fruit flies are super easy to breed and show significant color variations, size of wings shapes etc. Interesting class. looks like you've got some super genetics going. Thanks
