WebGenetic drift is a mechanism of evolution in which allele frequencies of a population change over generations due to chance (sampling error). Genetic drift occurs in all populations of non-infinite size, but its effects are strongest in small populations. WebArtificial selection is human selecting for traits they find favorable. For example: Corn has two varieties: thin/small seeds vs fat/plump seeds. Farmers have utilized artificial selection to produce majority plump kernels by constantly planting plump seeds so over time majority of the population has plump seeds. How is artificial selection
WebNatural selection. Finally, the most famous mechanism of evolution! Natural selection occurs when one allele (or combination of alleles of different genes) makes an organism more or less fit, that is, able to survive and reproduce in a given environment. If an allele reduces fitness, its frequency will tend to drop from one generation to the next. WebMutation, migration, genetic drift, and natural selection are all processes that can directly affect gene frequencies in a population. Imagine that you observe an increase in the frequency of brown coloration genes and a decrease in the frequency of green coloration genes in a ...

WebDuring artificial selection, humans choose parent organisms with specific traits and allow them to reproduce. This is repeated over many generations. Eventually, this process gives rise to new types of organisms. The types of organisms that result from artificial selection are considered domesticated.
