title: 'hybridclock: How Long Have Hybrids Been Forming? Hybrid Population Histories
  from Diagnostic Markers'
version: 0.1.1.9000
identifiers:
- type: doi
  value: 10.32614/CRAN.package.hybridclock
abstract: 'Estimates the history of hybrid populations from diagnostic markers, with
  or without a genetic map: the average age of the hybrids, how long ago the rarer
  species'' ancestry entered, the number of backcrosses, and whether pure animals
  of the rarer species are still arriving. Population samples of hybrid index and
  interspecies heterozygosity, as defined by Fitzpatrick (2012) <https://doi.org/10.1186/1471-2148-12-131>,
  are compared with forward simulations that include drift, small breeding groups,
  sibling mating and separate breeding pools, so that inbreeding is not mistaken for
  age. Estimates come from ''Cubist'' models with split-conformal intervals. Recent
  hybrids are also classified individually, and the number of markers needed to detect
  backcrossed hybrids follows Boecklen and Howard (1997) <https://doi.org/10.1890/0012-9658(1997)078[2611:GAOHZN]2.0.CO;2>.'
