Fig. 2From: Noninvasive and nondestructive sampling for avian microsatellite genotyping: a case study on the vulnerable Chinese Egret (Egretta eulophotes)Sample quality index (SQI) of different DNA sources. Indices for each sample type are sorted in ascending order. For plucked feathers and eggshell swabs, only the first 16 indices can be shown and those not shown are all equal to 1.0. The SQI of different sample types may overlap when they are equal to 1.0Back to article page
