The function create_GSP() allows the user to quickly create several different pedigree structures that are “saturated” in the sense of using all the genomic material of the founders. There are 15 different pedigrees, and they can be specified by the user according to whether the user wants to have any of the following four hybrid categories to be present amongst the simulated descendants:

• F1: a first generation F1 hybrid—the product of mating between two parentals, one from population p1 and the other from population p2.
• F2: the product of a mating between two F1s
• F1B: an F1-backcross—the product of a mating between an F1 and a parental (non-admixed) individual from population p1.
• F1B2: a second-generation F1-backcross—the product of a mating between an F1B and another parental from population p1.

The following images show the pedigrees created by create_GSP() with different inputs (TRUE or FALSE) for the four parameters, F1, F2, F1B, F1B2, to the function.

See the documentation ?create_GSP for more information.
