Deviation from Mendelian Genetics

Post by SauronTheConqueror » Thu Jan 21, 2010 2:49 pm

It is generally known that the expression of flower colour in Mirabilis jalapa shows incomplete dominance of Red colour over white. I also read a conflicting article that the deviation may due to the role of extra nuclear DNA that is thought to play a role in determining the somatic characters. Can somebody kindly clarify this doubt as to the cause of this apparent discrepancy. Also what are kappa particles?

what paper?

Edit: Remember that mendelian genetics deals with inheritance, but dominance is dealing with expression of genes so you might have some epigenetic effects in play here.

yeah even i have heard that an extra DNA does make a difference.
it isn't what you do that matters but it is how you do it
