Sexual reproduction
Each individual’s genotype consists of a number of diploid, biallelic loci. A subset of these loci, np contributes to an individual’s phenotype; nc are involved in incompatibility; nn are neutral and used to track the recipient genome; and nh are used to score the heterozygosity of each locus through time. We differentiate between loci used to track the recipient genome and those used to track heterozygosity in order to compare two contrasting management objectives. Each offspring’s genotype is a result of the fusion of gametes from a ‘male’ and ‘female’ parent. Genetic recombination is based on an algorithm described by Kelly et al. (2018) in which the genome wide recombination rate is calculated as the average proportion of pairwise crossover events between loci.
