Want this question answered?
One standard deviation.
sample data drawn from one population is completely unrelated to the selection of sample data from the other population.
true
No, the two of them used algebra and probability to model population biology, not natural selection, however similar the two may be.
The method will depend on what the population comprises. For example, if every element in the population has multiple properties then simply random selection will suffice.
Directional selection.
Directional Selection
Natural selection requires that individuals in a population are
Adaptive change is the province of natural selection and natural selection is one of the main drivers of evolution. Natural selection selects from the individuals variations in a population of organisms on, basically, reproductive success and this adaption is passed on to progeny which changes the allele frequency in the population which is evolution.
different ways in which individuals with particular trait may increase are -if that particular trait provides them with some sort of support to undergo the circumstances they are found in, we can also call it natural selection -or due to any genetic drift, that is a natural calamity, also called a chance selection
In the next generation that trait increases in frequency above the frequency in the current generation.
Tends to result in a population whose individuals have extreme traits is what? ----> it is directional selection
- natural selection - sexual selection - genetic drift - immigration/emagration
stabilizing selection
A type of natural selection in which genetic diversity decreases as the population stabilizes on a particular trait value.
By favoring one variation of organism over another variation in the same population. These favored individuals ( natural selection selects individual organisms ) leave more descendants, with these traits, who over time become more numerous in the population and the populations allele frequency changes to reflect this. In a word, evolution.
