SNPtrio is a web-based tool that allows visualization of uniparental inheritance segments (uniparental disomy, hemizygous or homozygous deletion, loss of transmitted allele, non-paternity, etc.), based on single nucleotide polymorphism (SNP) genotype calls of father-mother-child trios.
SNPtrio produces a plot of "informative" SNPs, as defined in the Heredity Table schema, at the size you specify, one track per trio. The dots on the plot are color-coded according to the schema listed in the Heredity Table. SNPtrio also provides information about informative SNPs in a text format, as well as the likelihood for each block found.
