as in being phenotypical? I found their research regarding the idea that triploids may be the perfect or more perfect chromosome count very illogical. they based their findings off the idea that these triploids were larger. but they weren't testing a trip and a tet of the same genetics. to me that's not a control at all. so lets leave the realm of triploids and say I want to isolate diploids that are believed to create 2n gamete if I then pollinated them to a tetraploid and line bred from there could I end up with a tet many years down the line that produced 4n gamete?
I've heard somatic double can be induced through stress during the development of buds such as temperatures above 110f?
