The difference in DNA sequence for most alleles, such as those in heterozygous individuals, was likely a result of that took place generations ago in an ancestor. Genetic Drift Natural Selection Mutation Inbreeding

Artificial selection is when people selectively choose individuals with a certain desired trait to use as parents of the next generation. It is done to domesticated (or semi-domesticated) organisms. It has produced such monstrosities as bubble-eyed goldfish, revealing the potential for selection acting on heritable variation to produce varieties appearing very different than their ancestors. How is that different from natural selection? (Select all that apply) A- In artificial selection, humans directly cause new mutations to occur, whereas natural selection relies on mutations that occur randomly over time. B- Artificial selection can lead to organisms that would be unfit to survive in the wild, whereas natural selection usually makes the population better adapted. C- Artificial selection is directed ahead of time towards an intentional goal; not so with natural selection. D- Really, they are exactly the same process. Both cause what seems to be design without a designer. E-…

natural selection is incorrect

An animal born with a shorter tail. This makes no difference to its ability to survive or reproduce, but as a result of pure luck, the animal survives, reproduces, and passes its shorter tail down to its offspring. Over time, the species develops a shorter tail. What type of process is described in this scenario? genetic modification artificial selection genetic drift natural selection

The neutral theory of evolution proposed that most genetic mutations are functionally neutral or nearly neutral. Neutral mutations would be fixed in a population by: O the invariance of DNA O random genetic drift O balancing selection natural selection asexual reproduction

Siberian tigers are the largest of all tiger species because only the largest individual are able to survive the cold harsh winters of north eastern Russia. what type Mechanism evolution is this Natural Selection Genetic drift Gene Flow Bottleneck Effect Founder Effect Sexual Selection

Which of these evolutionary processes can increase allelic variation in the population? O Mutation Natural Selection Artificial selection Sexual selection

Match Column A with Column B. The ultimate source of new alleles A. Mutation this force is causing a small percentage to the evolution process B. Natural selection most are lost due to chance or to detrimental effects on C. Genetic drift phenotype D. migration |In its absence, allele frequencies in different subpopulations will diverge Source of new alleles entering local population from other subpopulations v The movement of organisms among subpopulations - v Genotypes best suited to survive and reproduce in a particular environment of the offspring | The genotypes that promote survival are favored and contribute disproportionately to the offspring of the next generation known as evolutionary adaptation | The random, undirected changes in allele frequencies, especially in small populations.

Which of the following is an example of genetic drift? Group of answer choices   A-As global temperatures increase, alleles that confer resistance to heat become more prevalent   B-Peter Parker gets irradiated and turns into Spider Man   C-The American Bison was hunted almost to extinction very quickly, and only a few remained   D-5% of your neighborhood moves to Canad
