I want to know whether my over-expression line is homo or heterozygous in genetic background. I know some methods but want to is there any way to find that.
Methods I know-
1. Check segregation in the T3 generation (but what if i dont have marker for the selection)
2. Design one primer in promoter (35S) region and other in gene region, and check the expression intensity (theoretically which may address the question). Higher intensity homo and low intensity hetero.
