Write your explanation of the role of genetics in Natural and Artificial Selection. Write on how environmental factors affect the survival based on Natural and Artificial Selection.

Answers

Natural selection is the survival of the fittest. Basically the organisms that best suit the environment they’re in will survive, and the less suited will pass. Artificial selection is when humans intervene and breed plants and animals to have desired traits. Like if one turtle has a longer neck than the other, and the plants are really tall in an area, people might selectively breed them so less turtles are dying of hunger.

Answers

Answer:

16. Directional Selection

17. Disruptive Selection

18. Stabilizing Selection

19. Natural Selection

20. Adaptation

Explanation:

In population genetics, directional selection/positive selection is a mode of natural selection in which an extreme phenotype is favored over other phenotypes.

Disruptive Selection would show phenotypes (individuals with groups of traits) of both extremes but have very few individuals in the middle.

Stabilizing Selection. Occurs when individuals at the extremes of the range of characteristic are selected against. This means that the "average" individuals are selected for.
