How does artificial selection in biology impact the genetic diversity of a population?
Artificial selection in biology can impact the genetic diversity of a population by favoring certain traits or characteristics in organisms, leading to the breeding of individuals with those desired traits. Over time, this can reduce the overall genetic diversity within the population as only specific traits are being selected for, potentially leading to a decrease in genetic variation.
How has artificial selection of dogs influenced the diversity and characteristics of different dog breeds?
Artificial selection of dogs has led to the creation of diverse dog breeds with specific characteristics through selective breeding practices. This has resulted in a wide range of sizes, shapes, coat types, and temperaments among different dog breeds.
What is one factor that affects natural selection and artificial selection?
Variation in the organisms under selection. In both artificial selection and natural selection there must be heritable variations that have the possibility of being in the case of artificial selection what the selector wants in the organism and in thje case of natural selection survivability and reproductive advantages.
What is balancing selection and how does it contribute to genetic diversity in biology?
Balancing selection is a type of natural selection that maintains genetic diversity by preserving different versions of a gene in a population. This occurs when multiple versions of a gene are advantageous in different environments or circumstances, preventing any one version from becoming fixed in the population. As a result, genetic diversity is maintained, allowing for adaptation to changing conditions and increasing the overall fitness of the population.
How has artificial selection influenced the diversity of dog breeds?
Artificial selection, where humans selectively breed dogs for specific traits, has led to the wide variety of dog breeds we see today. This process has created breeds with distinct physical characteristics, behaviors, and abilities, resulting in a diverse range of dogs suited for different purposes and preferences.
What drives the rate of diversity change?
Natural selection, Evolution, Artificial selection, disasters
How does natural selection contribute to biological evolution?
Selection is not always of the most fit to survive.
How do mutations natural selection geographic isolation genetic drift and migration contribute to biological evolution?
they contribute to biological evolution by how they've affected the evolution rate by increasing it or decreasing it

How is artificial selectio different than natural selection?
Artificial selection is the process by which humans intentionally breed plants or animals for specific traits, whereas natural selection occurs naturally in the wild, favoring individuals that are better adapted to their environment. In artificial selection, humans make the decisions about which organisms reproduce based on desired characteristics, while in natural selection, the environment shapes the survival and reproduction of organisms. This leads to different outcomes in genetic diversity and adaptation, with artificial selection often resulting in a narrower gene pool.
Compare and contrast natural selection and artificial selection?
Natural selection is when contemporary species rose from ancestors that survived due to their physical characteristics in their habitats. A well-known example is the Galapagos Islands and how the animals on the islands adapted to their environments. Darwin convinced the biology world that diversity in organisms came from evolution (descent without modification). Artificial selection is when humans intentionally breed animals for certain traits. Unlike natural selection, where only the fittest survive, artificial selection is for human's likings. Many crops that are grown are part of artificial selection.
When was Some theorems on artificial selection created?
Some theorems on artificial selection was created in 1934.
What role does the environment play on natural selection?
Nature plays no direct role in artificial selection. That is the difference between artificial selection and natural selection. Nature does play some indirect roles in artificial selection. One indirect role is in providing the organisms with which one beings the artificial selection. Another is in influencing the choices of the organism performing the artificial selection.

How is genetic diversity important to the concept of natural selection?
Without genetic diversity, natural selection cannot occur
Type of selection in which human select the variation?
Artificial selection.
