Fig. 5From: Scoring the number of B chromosomes in Zea mays L. using droplet digital PCR assayScoring the B chromosome copy number using ddPCR technique in wild maize landraces. Each estimate of the number of B chromosomes (Y-axis) is based on a CNV measurement from a single ddPCR well of > 10,000 droplets. Error bars indicate the Poisson 95% confidence intervals for each copy number measurementBack to article page
