#' FORCE panel kinship SNPs
#'
#' A data frame describing (a subset of) the FORCE panel of SNPs designed for
#' applications in forensic genetics (Tillmar et al., 2021). The subset included
#' here are the SNPs recommended for kinship analysis. As the original
#' publication did not include allele frequencies, these were downloaded from
#' Ensembl via the biomaRt package. 15 markers were removed as frequency
#' information could not be retrieved.
#'
#' To attach the FORCE markers to a pedigree, use [pedtools::setSNPs()] (see
#' Examples).
#'
#'
#' @format A data frame with 3915 rows and 6 columns:
#'
#'   * `CHROM`: Chromosome (1-22)
#'
#'   * `MARKER`: Marker name (rs number)
#'
#'   * `MB`: Physical position in megabases (build GRCh38)
#'
#'   * `A1`: First allele
#'
#'   * `A2`: Second allele
#'
#'   * `FREQ1`: Allele frequency of `A1`
