Flashcards on Heredity and Evolution

Click on the flashcard to see the answer


What is heredity?

Heredity is the passing on of traits from parents to offspring through genes.

What is a gene?

A gene is a segment of DNA that contains the instructions for building a specific protein or trait.

What is evolution?

Evolution is the process of change in all forms of life over generations.

What is natural selection?

Natural selection is the process whereby organisms better adapted to their environment tend to survive and produce more offspring.

What is genetic variation?

Genetic variation refers to the diversity in gene frequencies and traits within a population.

What are mutations?

Mutations are random changes in the DNA sequence that can lead to new traits or variations in organisms.

What is selective breeding?

Selective breeding is the intentional mating of organisms with desirable traits to produce offspring with those traits.

What is adaptation?

Adaptation is the process by which organisms become better suited to their environment.

What is speciation?

Speciation is the process by which new species evolve from existing species over time.

What is genetic drift?

Genetic drift is the random change in gene frequencies due to chance events.

What is the role of DNA in heredity?

DNA contains the genetic information that determines an organism's traits and is passed on from parent to offspring.

What is the difference between inherited traits and acquired traits?

Inherited traits are passed on from parents to offspring through genes, while acquired traits are learned or developed during an organism's lifetime.

What is genetic engineering?

Genetic engineering is the manipulation of an organism's genes to introduce new traits or modify existing ones.

What are fossils?

Fossils are the preserved remains or traces of organisms that lived in the past.

What is the role of mutations in evolution?

Mutations provide the genetic variation that is necessary for evolution to occur.
