Cultural transmission (CT) refers to the transmission of environmental factors that are related to the trait (e.g., general intelligence) from the parental generation to the offspring generation, and is shared between siblings.
There are pictures of families persistently graced with identical offspring, generation after generation.
After they are bred with their predetermined mates, their offspring, generation F1, will be grown in captivity to adulthood.
To accommodate the stochastic nature, we adapt a ranking-and-selection procedure to construct an elite chromosome set in each generation of the genetic algorithm, and use the elite chromosome set to improve the offspring generation.
To deal with the potential high dimensional optimization problem (i.e. large transition matrices), an enhanced offspring generation procedure is proposed to help the ES algorithm converge efficiently and find better Pareto frontiers through generations.
Meanwhile, all other parents will be replaced by the offspring generation.
Cultural evolutionists agree that at the level of the population, cumulative evolution requires that fitness-enhancing cultural traits are preserved in the offspring generation.
A common complementary technique, often adopted to speed-up the convergence, denoted as elitism, is the process of selecting the better individuals to form the parents in the offspring generation.
The left-hand side represents the allele frequencies in the parental generation and a random mating pattern, while the right-hand side captures genotype frequencies in the offspring generation, as predicted from the parental generation.
This is a null theoretical model actual genotypic and allelic frequencies of the offspring generation often deviate from predicted frequencies (e.g., a lethal homozygote recessive would make the \ q^2_{\text{off}}\) term = 0).
Generations are non-overlapping and the offspring generation is selected following a Wright-Fisher sampling at each time step.
