Sentence examples for selection variation from inspiring English sources

Due to drift and selection, variation in fitness in these populations might have been too small to select for choosier males.

Darwin's model (quoted above) primarily explicates the now well-known requirements for natural selection: variation, heritability, and differential survival.

Students play crab by clicking on snails to eat them, and can use checkboxes to enable and disable conditions that contribute to natural selection (variation, heritability, differential survival/reproduction).

In our course, we preceded the human evolution discussion with a lecture that emphasized there are three requirements for natural selection: variation for a trait in a population, heritability of the trait, and differential reproductive success.

"Neutral theory and genetic drift" was the topic for one lecture (out of 18) and there was an associated class on "selection, variation and drift" spread over two recitation periods (out of 16).

Our results demonstrate that both simulations were effective in increasing students' knowledge of the key components of natural selection: variation, heritability, and differential reproductive success, based on their improved performance on a post-test and delayed post-test compared to their pre-test (Fig. 1).

In addition to natural selection, variations in the rate and direction of both mutation and DNA repair can also have a major impact on the patterns of sequence divergence.

These forces could include frequent balancing selection and variation of mutation rates between coding genes and non-coding intergenic regions.

representation (definition of individuals); evaluation function (or fitness function); population; parent selection mechanism; variation operators (recombination and mutation); survivor selection mechanism (replacement).

Because most calculated ω values indicate negative selection, and variation of α has stronger influence under negative selection, we analyzed the variation of ω in a range of 0.1 to 0.9 to evaluate the effect of α on ω.

Now that we know how "spontaneous" variations arise, it is time to recognize that we cannot have selection without variation by natural genetic engineering and epigenetic modifications.
