Genetic Predictor Options

Use this to specify options for calculating the genetic predictors for a QTL analysis.

Maximum step size along genome

This specifies a maximum step size in cM to use for the calculation of the conditional probabilities. Setting this to a large value, such as the default value of 10⁶, will calculate the IBD probabilities only at the marker positions.

Mapping function

This specifies the mapping function used. You can select either Haldane or Kosambi.

Available data

This lists text data structures currently available in Genstat appropriate for the labels for genotypes. Double-click a name to copy it to the current input field or type the name.

Labels for genotypes

A text specifying labels for the genotypes that correspond with the labels for the genotypes for the phenotypic means. This data structure can be used to ensure that there is correct matching for the genotypes between genotypic and phenotypic data. If a data structure exists in the QTL data space for the labels for genotypes then this will be automatically entered in the field.

Save genetic predictors into QTL data space

When the results are saved the data structure names will be added to the QTL data space so that the names of the structures will be present in the QTL menus.
