F6 generation of self pollination

[snapdragon]

Is there any works of mendels related to F6 generation and its observations? 

[poo thrower]

no... because that is called "inbreeding depression to the point of "why would you even want to do that"" ?.

if you s1, 1x then you already have homozygous offspring... ("randomly assortment of").

mendel worked on phenotype because "nobody prior to him" (?) knew about patterns passed to progeny (...and now nobody nowadays will believe we can be read like peaplants).
