Selective breeding (also called artificial selection) is the process by which humans use animal breeding and plant breeding to selectively develop particular phenotypic traits (characteristics) by choosing which typically animal or plant males and females will sexually reproduce and have offspring together.

What do you mean by natural selection?

Natural selection is the process through which populations of living organisms adapt and change. Individuals in a population are naturally variable, meaning that they are all different in some ways. Individuals with adaptive traits—traits that give them some advantage—are more likely to survive and reproduce.

What are advantages of natural selection?

Through this process of natural selection, favorable traits are transmitted through generations. Natural selection can lead to speciation, where one species gives rise to a new and distinctly different species. It is one of the processes that drives evolution and helps to explain the diversity of life on Earth.

Why is the evolutionary theory important?

Knowing the evolutionary relationships among species allows scientists to choose appropriate organisms for the study of diseases, such as HIV. Scientists are even using the principles of natural selection to identify new drugs for detecting and treating diseases such as cancer.

Is natural selection a process?

Natural selection is the process through which populations of living organisms adapt and change. Individuals in a population are naturally variable, meaning that they are all different in some ways. This variation means that some individuals have traits better suited to the environment than others.

Is artificial selection good or bad?

Although it has provided some benefits for humans, the domestication of animals through the use of artificial selection is unethical as it has sometimes been detrimental to the animals’ well-being. This process, although beneficial to society, is unethical as it benefits humans at the cost of these animals’ wellbeing.

What is artificial selection simple definition?

Artificial selection is the identification by humans of desirable traits in plants and animals, and the steps taken to enhance and perpetuate those traits in future generations.

Which is the best definition of selective advantage?

(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.

What are the advantages of a good selection process?
