#' Gut length intercross data
#'
#' Data from a mouse intercross experiment on gut length, including both sexes.
#' All individuals carry the \eqn{Sox10^{Dom}}{Sox10Dom} mutation.
#'
#' A mouse intercross between C3HeBFeJ (C3) and C57BL/6J (B6), with one F1
#' parent carrying the \eqn{Sox10^{Dom}}{Sox10Dom} mutation.  There are 1068
#' mice from reciprocal intercrosses.  Over 2000 mice were generated, but only
#' those individuals heterozygous at \eqn{Sox10^{Dom}}{Sox10Dom} were genotyped
#' and included in the data set. \eqn{Sox10} is on chromosome 15, and so that
#' chromosome exhibits an unusual segregation pattern.  Some mice received the
#' mutation from their mother and some from their father.
#'
#' The primary phenotype here is gut length (in cm).  The phenotype
#' `cross` indicates the cross used to generate an animal.
#'
#' @format An object of class `cross`.  See [qtl::read.cross()]
#' for details.
