More than 5 sepals are frequently observed on tomatoes especially commercial varieties. Do you think this can be the unwanted result of mutagenesis applied during the plant's breeding program?

Thanks!!
Thank you Wajid for this rich and interesting litterature but too complex for me and not enough linked to my subject. I do not find informations about supernumerary sepals. Thank you for the contribution and to enlarge the discussion
Hi
I do think that it's a result of the breeding program, but I wouldn't call it (unwanted) as far as it is only morphological, especially that this supernumerary might be genetically linked with the traits that we want in the first place.
I hope I've understood the question correctly.
best regards.
Michael, what do you mean by genetically linked? two genes on the same chromosome with two mutations affecting each one? a single mutation affecting both genes? a single gene and a single mutation but affecting two traits including supernumerary sepals)?
Hi
I meant that this could be a case of two ( or more) mutations on the same chromosome for two linked genes or set of linked genes one for the number of sepals and one for the wanted trait when using non specific mutating methods.
