In sum, 84 percent of the progeny have the parental combinations of traits, and 16 percent have the traits recombined.
The introduction of new alleles through gene flow increases variability within the population and makes possible new combinations of traits.
Sex provides variety by mixing genes from two parents, producing combinations of traits in their offspring that they do not show themselves.
In the 1940s many investigators focused on intensive studies of individual traits and of combinations of traits that seemed to define personality types, such as the "authoritarian personality".
They then fed this smorgasbord of data, far more than any human being could hope to process, into their computers, and told the machines to look for combinations of traits that predict whether a particular species is likely to harbour something that can cause human disease.They duly found some.
During the evolution of reproduction and variation, which are the two basic properties of organisms that not only are required for natural selection but are also subject to it, sexual reproduction has become ideally adapted to produce the right amount of variation and to allow new combinations of traits to be rapidly incorporated into an individual.
These predictions could drive breeders or genetic engineers towards producing plants with these combinations of traits, so that the models can be tested experimentally.
The purpose of the phenotyping experiments was to scan the population for multiple traits and combinations of traits captured at a relatively early generation (S4).
Structural-functional plant models based on an economy of resources allow us to identify potential combinations of traits that can increase plant growth under a wide variety of environmental conditions, including water or nutrient poor conditions.
In the case of modularity, it means that among gene variants that affect different numbers of traits, those gene variants are selected which affect lower numbers of traits, as well as certain combinations of traits.
