Assignment of sculpins to their population of origin based on body shape. A model based only on the differentiation of parental populations is very effective in identifying pure sculpins but assigns the majority of hybrids to pure populations as false positives. A more complex model that includes the shape components specific to hybrids correctly identifies the majority of all hybrids. The overall success of parental group assignment is decreased when hybrids are taken into account as they overlap with parental phenotypic values. | |||||
