12 Questions
What is the term used to describe the changes in the sequence of DNA that may lead to evident or intangible changes in physical traits?
Mutation
Which process allows an organism to survive despite rapid changes in its surroundings?
Natural selection
What is the term for the set of all genes in a population that changes when the population evolves?
Gene pool
Which individual cannot evolve according to the text?
An individual without any changes in its genetic material
What is the process that allows the inheritance of some traits from parents to offspring?
Recombination
Which process often leads to the emergence of new species?
Speciation
What is the primary factor affecting the genetic makeup of an entire population?
Natural selection
How does evolution cause changes in a population?
By altering the genetic materials of individuals
Which of the following mechanisms involve the intentional selection of desired traits by humans?
Artificial selection
Which process leads to changes in a population's gene pool due to random sampling effects?
Genetic drift
Which mechanism involves the selection of traits that confer a reproductive advantage in a given environment?
Natural selection
Which process involves the shuffling of genetic material to create new combinations of alleles?
Recombination
Study Notes
- Evolution is the process of genetic changes in populations that are passed on to successive generations, resulting in physical trait shifts and adaptations for survival.
- Populations are groups of individuals from the same species capable of interbreeding and passing on adaptive changes to offspring.
- Adaptations are beneficial traits that enhance an organism's ability to survive in its environment.
- Both natural and artificial selection are primary factors that cause genetic changes in populations.
- Natural selection refers to the process by which organisms with advantageous traits survive and pass on those traits to their offspring, while artificial selection is the intentional breeding of organisms for specific traits.
- Evolution leads to speciation, the emergence of new species through genetic changes and divergence from a common ancestor.
- In the presented activity, students will breed organisms to achieve specific traits, practicing their crossing skills and understanding the concept of inheritance.
Test your knowledge on genetic changes in populations that are passed on to successive generations and how they lead to adaptations for survival. Explore the mechanisms of population change such as artificial and natural selection.
