Document Summary

If individuals die who would they be: there has to be variation in population. Variation in a population: adaptation, some individuals are better suited to their environment than others. definition: natural selection, is the whole process in which some individuals are more better than others, the mechanism in which evolution occurs. What facts form the base of our understanding of evolution: for a characteristic to evolve the variation must be heritable, genotype- the genetic makeup of an organism www. notesolution. com. Biology i i: the genetic coding for a trait, phenotype- the physical expression of an organism"s genes, physical appearance, character- a particular feature of the individual"s phenotype, trait- a specific form of a character. Biology i i: founder effect- almost the same as bottleneck. one species leave and move to a new region. In the new population they will have the same phenotypes: non-random mating-when individuals choose mates with particular phenotypes.
