I ordered Arabidopsis mutants from ABRC and found that one of the mutant is hetrozygous (confirmed by genotyping), later when I performed qPCR, I did not see any amplification of that particular gene (undetermined values). What can be the reason ?
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...
