Web11. apr 2024 · A chromosome is partitioned into regulatory loci and structural loci. The regulatory genes regulate the expression and functioning of structural genes via the cis-elements in a probabilistic manner. In the simulation, the change in the allele frequency, the mean population fitness and the efficiency of phenotypic selection are monitored. Web20. máj 2024 · Offspring with traits that make them more likely to survive, mature, and reproduce in the environment they inhabit pass on their traits to the next generation. As this happens generation after generation, natural selection acts as a kind of sieve, or a remover of undesirable traits.
