Admixed Population Dominant Genotype Data from Simulation 1

Description

This data set contains genotypes for a simulated admixed population. The simulated admixed populations conisted of 500 diploid hermaphroditic individuals with ten pairs of chromosomes, each one Morgan in length. The admixed population resulted from an intitial hybridization event between two parental populations (combined in equal proportions) and mating within the admixed population continued for five additional generations. Fitness of hybrids was determined based on a marker at the center of chromosome 1; individuals homozygous at this location had a fitness of 1, while heterozygotes had of fitness of 0.1. Two hundred admixed individuals were sampled at the completion of the simulation and scored for 110 dominant markers spaced evenly across all 10 linkage groups (at 10 cM intervals). Alleles inherited from parental population 1 were treated as the dominant alleles.

The data are provided as a matrix with rows and columns corresponding to markers and individuals, respectively. For each marker an individuals genotype is given by a 1 (homozygous for population 1 alleles or heterozygous) or 0 (homozygous for population 2 alleles).
