Document Summary

I. e variants best suited for survival will display in heavier proportions in the next generations: ex. Farmers have us1ed this for thousands of years to yield a higher crop or to try to improve resistance to droughts, disease or other changes to the environment. Also how dog breeding works and how antibiotic resistance is on the rise in many disease-causing microorganisms: variation is commonplace and we scarcely pay attention to it, environmental variation: variation among individuals due to differences in the environment. Ex. exposure to sunlight as apples grow on a tree or escaping moths/caterpillars: genetic variation: variation due to differences in the genetic material that is transmitted from parents to offspring. Differences in dna lead to differences among rna and proteins which affect molecular functions of the cell and can lead to physical differences (phenotypes). Ex. genetic differences in apples produce a variety of tastes and colour (granny.
