Fig. 3From: Scoring the number of B chromosomes in Zea mays L. using droplet digital PCR assayCopy-number results of B chromosome scoring in reference set using ddPCR technique. The value of the estimated number of B chromosomes (copy number; Y-axis) as calculated from ddPCR analysis in each plant (ID in x-axis) over the entire range of values examined. Each estimate 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
