InDelGT

InDelGT genotypes insertion and deletion (indel) variants from next-generation sequencing (NGS) data to enable indel-based genetic mapping in hybrid and segregating populations.

Key Features:

• Integrated pipeline: Processes NGS data through three main steps: generating an indel catalog, calling indel genotypes across individuals, and analyzing indel segregation.
• Segregating population support: Tailored for backcross, F2 lines, and F1 crosses between outbred species.
• Mendelian segregation analysis: Genotypes large numbers of indel markers and evaluates adherence to Mendelian segregation patterns for linkage analysis.
• Linkage map construction demonstration: Applied to an F1 hybrid population of Populus to construct parental genetic linkage maps.

Scientific Applications:

• Genetic linkage mapping: Supports construction of genetic linkage maps from indel markers in segregating populations.
• Quantitative trait locus (QTL) identification: Enables identification of QTL underlying complex traits using indel segregation data.
• Plant breeding: Facilitates analysis of indel polymorphisms relevant to breeding and trait mapping in plants.
• Evolutionary biology: Supports studies of genetic variation and inheritance in hybrid and outbred populations.
• Conservation genetics: Enables assessment of indel polymorphisms for population genetics and conservation studies.

Methodology:

Processes next-generation sequencing (NGS) data through three computational steps: generating an indel catalog, calling indel genotypes across individuals, and analyzing indel segregation.
