Reproduction
What cell process does asexual reproduction use, resulting in clones?
Mitosis
Human weight is an example of _____________ variation.
Continuous
Humans breeding dogs to look different is an example of ____________ selection
Artificial
True or false: A population with a lot of genetic diversity is more likely to survive changing environmental conditions?
True
What cell process does sexual reproduction use, resulting in the formation of gametes (sperm, eggs)?
Meiosis
Eye colour is an example of _____________ variation.
Discrete
Birds beaks evolving over time to catch different types of food is an example of ____________ selection
Natural
True or false: Offspring might display different traits than their parents
True: e.g., eye colour, hair colour
What is one benefit of asexual reproduction?
Quick, efficient, good for well-adapted organisms
The differences between black bears, grizzly bears and polar bears would all be variation ____________ species.
Between
What is artificial selection/selective breeding?
Humans are controlling breeding to create desirable traits
True or false: The presence of a dominant trait might mask the other (recessive) copy of the trait, but that copy is still present in the organism's genes.
True
What is one benefit of sexual reproduction
Diversity, variation, evolution
The differences in hair colour in our class would be an example of variation ___________ species.
Within
What is natural selection?
When the environment, over time. "chooses" the best traits for organisms in an environment.
What is it called when one gene (e.g., brown eyes) is "stronger" than the other copy (e.g., blue eyes)?
Dominant
Provide an example of continuous and discrete variation
Continuous: has a range of values
Discrete: can be one or the other
Describe an example of artificial selection or natural selection
Artificial: e.g., on farms
Natural: changes in nature
What is the full name of DNA?
Deoxyribonucleic acid
