%description
Individual based simulations of hybridizing populations, where the
accumulation of junctions is tracked. Furthermore, mathematical equations
are provided to verify simulation outcomes. Both simulations and
mathematical equations are based on Janzen (2018, <doi:10.1101/058107>)
and Janzen (2020, <doi:10.1101/2020.09.10.292441>).
