Unreliable mtDNA data due to nuclear insertions: a cautionary tale from analysis of humans and other great apes.

abstract：:Variance in reproductive success is a major determinant of the degree of genetic drift in a population. While many plants and animals exhibit high variance in their number of progeny, far less is known about these distributions for microorganisms. Here, we used a strain barcoding approach to quantify variability in of...
