Sentence examples for constant over generations from inspiring English sources
Given that species remain largely constant over generations, how and why do they sometimes vary?
Sexual reproduction has no inherent tendency to destroy the genotypic variation present in the population, for the genotypic proportions remain constant over generations, given the assumptions noted above.
Keeping the chromosome number of a species constant over generations is a critical aspect of genetic stability.
However, the value of π(Qq| M ij ) was not conditioned on the phenotypes in the population, so once calculated, the π(Qq| M ij ) remains constant over generations for each QTL position.
Values with the same letter are not significantly different at P = 0.001 The selection accuracy with RRS was very high and remained constant over generations, i.e. around 0.967 ± 0.003 (SD), with a negligible effect of trait and population (not shown).
Züst et al. [ 43], working with Arabidopsis populations and aphids (a generalist phloem-feeder), reported that the trichome densities of Arabidopsis plants in presence of herbivores remains constant over generations and decrease in an herbivore free environment.
When the IND sire model gives a higher log-likelihood than the animal-HOM model and the IC model gives a higher likelihood than the animal-CLASS model, this implies that the true genetic variance is constant or increasing over generations instead of decreasing because of the accumulation of inbreeding.
We did not consider overlapping generations and the number of individuals per population was kept constant over successive generations.
Another possible explanation for how the net number of CSCs remains constant over multiple generations in established cancer cell lines or in tumors is that the epigenetic status of two cell types is flexible and able to switch from one type to the other.
It is further assumed that the association between PrP genotype and lamb mortality is due to pleiotropy rather than linkage, implying that the associations remains constant over successive generations.
Hence k E is constant over the generations through the evolutionary process.
