For reasons that are unclear, in scenarios involving small versus large Nb (Nb = 24 vs. 50 or 100), small Nb populations also lost rarer alleles more readily than that predicted by the discrete generation model in the early generations, but this effect disappeared after about 10 generations (details in Waples 1990).
There was a less prominent effect on airway eosinophilic inflammation and IgE-level in the F2 generation, and this effect was transmitted paternally.
Based on the above considerations, this work was undertaken to investigate the effects of 7-hydroxy-3,4-dihydrocadalin in streptozotocin-induced diabetic rats and mice without blood glucose control as well as the possible participation of opioid, serotonergic, nitrergic and antioxidant systems in the generation of this effect.
We should therefore expect that the F2 and the RIL generations might show higher phenotypic variance than for example the P1, P2, or F1 generations (all three of which are genetically identical within generations and thus will have low variance relative to other generations), and this effect will be exaggerated in RIL compared to the F2 because all individuals are homozygous at virtually all loci.
Similarly, in the context of the K-Ras G12V lung carcinogenesis mouse model, telomerase deficiency decreased tumor growth only after five mouse generations, and this effect was lost upon p53 abrogation (Perera et al, 2008).
The accuracy of selection increases when more information on the marker effects becomes available over generations, and this effect is larger in the selection scheme than in the random selection scheme, probably because the favourable alleles become more abundant and are thus more accurately estimated.
While, in this paper, we discuss the influence of volcanic areas on earthquake generation, the effect of this earthquake sequence on the volcanic activities should also be investigated.
21, 42 Though some reports suggest zerumbone to induce ROS generation, 43, 44 this effect was observed only with a prolonged exposure to zerumbone (24 h) and at higher concentrations (>30 μmol/L).
Assuming a low number of cells with an advantageous mutation in the original BSA pool, a shorter selection time (e.g., 10 30 generations) might alleviate this effect.
Maternal high-fat diet in mice results in an increase in body size of female third-generation offspring, and this effect was passed on only via the paternal lineage (30).
