I am researching the phenomenon where someone can be DNA tested say by blood sample and say buccal cells and a mismatch occurs in one allele. That is proven by repeating at different times and techniques. I assume it occurs in mitosis at or between oogenesis and stem cell generation to produce diffent cell lines.
Would anyone know how frequently this is observed and what the effect is called. ?
In paternity testing there is the accepted rate of allele disparity between offspring and parents is 1 in 1000 generations.
