Natural Selection and Selective Breeding

What is natural selection?

• The process of organisms randomly changing their traits

• The process of artificially selecting traits in organisms

• The process of organisms adapting to their environment through conscious effort

• The process where organisms better adapted to their environment tend to survive and produce more offspring.

Explain the process of selective breeding.

• Selective breeding is the process of choosing specific organisms with desirable traits to breed and produce offspring with those traits.

• Selective breeding is the process of breeding organisms with random traits.

• Selective breeding is the process of randomly mating organisms without considering their traits.

• Selective breeding involves only choosing organisms with undesirable traits to breed.

What are the factors that contribute to natural selection?

• Genetic variation, overproduction of offspring, struggle for existence, and differential survival and reproduction

• Predation, competition, and cooperation

• Random mutation, genetic engineering, and artificial selection

• Climate change, migration, and extinction

Give an example of natural selection in action.

• Giraffes growing longer necks to reach higher leaves

• Peppered moth in England during the industrial revolution

• Dogs being bred for specific traits by humans

• Birds changing color to blend in with their environment

How does selective breeding differ from natural selection?

• Selective breeding and natural selection are the same process with different names.

• Selective breeding is driven by environmental factors, while natural selection is controlled by humans.

• Selective breeding is controlled by humans, while natural selection is driven by environmental factors.

• Selective breeding occurs in the wild, while natural selection occurs in controlled environments.

What are the benefits of selective breeding?

• Decreased productivity, worsened quality, and weaker resistance to diseases and environmental conditions

• No impact on productivity, quality, or resistance to diseases and environmental conditions

• Increased cost, reduced variety, and limited adaptability to environmental changes

• Increased productivity, improved quality, and better resistance to diseases and environmental conditions

What are the drawbacks of selective breeding?

• Increased genetic diversity, decreased susceptibility to diseases, and intended positive traits

• Reduced genetic diversity, increased susceptibility to diseases, and unintended negative traits

• No impact on genetic diversity, decreased susceptibility to diseases, and intended negative traits

• No drawbacks, only benefits in terms of genetic diversity, disease resistance, and desired traits

How does natural selection lead to evolution?

• By causing all organisms to develop the same traits

• By preventing any changes in an organism's traits

• By favoring traits that increase an organism's chances of survival and reproduction

• By randomly changing an organism's DNA

What role does human intervention play in selective breeding?

• Allowing organisms to breed randomly without any interference

• Using genetic engineering to create desired traits in organisms

• Letting nature take its course without any human involvement

• Choosing which organisms to breed based on desired traits

Discuss the ethical considerations of selective breeding.

• Selective breeding has no impact on animal welfare

• Genetic diversity is not a concern with selective breeding

• Selective breeding raises ethical concerns related to animal welfare, genetic diversity, and potential harm to the species.

• Selective breeding always benefits the species
