What is an example of a selective agent?

Reproduction - Organisms that survive are able to reproduce and pass on their favourable genes to their offspring. One of the best known examples of natural selection in action is the peppered moth. ... The selective agent he observed preying on the moths were birds.

What are 4 different selective agents?

Resource availability: Presence of sufficient food, habitat and mates. Environmental conditions: Temperature, weather conditions or geographical access. Biological factors: Predation and disease.

What are selection agents?

Selection pressures are external agents which affect an organism's ability to survive in a given environment. Selection pressures can be negative (decreases the occurrence of a trait) or positive (increases the proportion of a trait)

What is an example of a selective advantage?

The genes that produce these characteristics give them a selective advantage . They may have a better ability to avoid predators, compete for food, or resist disease. ... Predation, competition and disease are examples of selection pressures.

What are selective forces?

Selective forces favor the individuals of both sexes who leave behind the most offspring. Oftentimes, this means that the two sexes will have different reproductive strategies. Stabilizing Selection. In this type of natural selection, individuals with extreme or unusual traits are selected against.

What are the five types of selective pressures?

There are several ways selection can affect population variation: stabilizing selection, directional selection, diversifying selection, frequency-dependent selection, and sexual selection.

What is the selective agent in artificial selection?

(not just evolution, a biotechnology!)

First, the selective agent in the case of natural selection is the environment generally whereas with artificial selection it is a specific aspect of an organism's environment, that is, humans in the case of domesticated organisms.

What is natural selection examples?

Natural selection is the process in nature by which organisms better adapted to their environment tend to survive and reproduce more than those less adapted to their environment. For example, treefrogs are sometimes eaten by snakes and birds.

What are the 3 types of natural selection?

There are three types of natural selection that can occur. Stabilizing selection, directional selection or disruptive selection.

What's an example of convergent evolution?

Convergent evolution is when different organisms independently evolve similar traits. For example, sharks and dolphins look relatively similar despite being entirely unrelated. ... Another lineage stayed put in the ocean, undergoing tweaks to become the modern shark.

What are the four main types of selection pressures?

Stabilizing, Directional, and Diversifying Selection. Stabilizing, directional, and diversifying selection either decrease, shift, or increase the genetic variance of a population.

What does a selective advantage do for an organism?

Filters. (biology) The characteristic of an organism that enables it to survive and reproduce better than other organisms in a population in a given environment; the basis for evolution by natural selection.

Is a gene a pool?

A gene pool is the total genetic diversity found within a population or a species. ... Inbreeding contributes to the creation of a small gene pool and makes populations or species more likely to go extinct when faced with some type of stress.

What is a selective advantage?

Any characteristic or trait that gives an organism or a genotype greater chances of surviving and reproducing than the available alternatives.
