Validation of two structural variants in 333 animals from four Chinese goat breeds by PCR amplification and agarose gel electrophoresis. a Agarose gel picture of the two PCR products (i.e., the 369-bp and 1822-bp fragments) for four horned, four polled, and four PIS-affected goats. Pattern 1 represented that the presence of only the 369-bp fragment; Pattern 2 represented the presence of only the 1822-bp fragment; the pattern 3 represented the presence of both the 369-bp and 1822-bp fragments. b Summary of the validation of two SVs in 333 samples from four Chinese goat breeds (i.e., JT, CB, TC, and NJ). Note: the total 333 samples included the animals with the WGS data, except for Bezoars
