Genetics and Evolution Vocabulary

Define Fitness.

• The range of genetic material present within a population or species.

• Fitness is the process of photosynthesis in plants.

• Fitness is the measure of an organism's intelligence.

• Fitness is the ability to fly in any environment.

Define Genetic Diversity.

• The relative ability of an organism to survive and reproduce in a given environment.

• The number of different species in an ecosystem.

• Genetic diversity is the process of genetic modification in organisms.

• Genetic diversity is the study of how traits are inherited from one generation to another.

Define Heritable.

• Heritable refers to  a trait or characteristic that increases an organism's fitness in a specific environment due to natural selection.

• Heritable refers to traits that are only acquired during an individual's lifetime and cannot be passed on.

• Heritable means traits that are influenced solely by environmental factors and not by genes.

• Heritable describes characteristics that are unique to each generation and never repeated.

Define Adaptation.

• Adaptation is the process of photosynthesis in plants.

• Traits or characteristics that can be passed from parents to offspring through genetic information.

• Adaptation is the movement of animals from one place to another.

• Adaptation is the breaking down of food in the stomach.

Define Selective pressure.

• Selective pressure is the tendency of organisms to migrate to new environments for better resources.

• Selective pressure is the process by which organisms choose their mates based on physical appearance.

• The gradual change in the genetic makeup of a population over generations, often driven by natural selection.

• Selective pressure is the random occurrence of genetic mutations in a population.

What is the term for the following definition? The process by which certain traits become more or less common in a population based on their impact on survival and reproduction.

• Natural selection

• Genetic drift

• Mutation

• Speciation

What is the term for the following definition? Factors in the environment that favor the survival and reproduction of certain individuals over others.

• Selective pressures

• Genetic drift

• Mutation rate

• Gene flow

Fill in the blank: Define the term 'Probability'.

• Probability is the measure of the likelihood that an event will occur.

• Probability is the process of collecting and analyzing data.

• Probability is the study of shapes and their properties.

• Probability is the calculation of speed and distance.

Fill in the blank: Define the term 'Advantageous trait'.

• An advantageous trait is a characteristic that improves an organism's ability to survive or reproduce in its environment.

• An advantageous trait is a feature that always makes an organism larger than others.

• An advantageous trait is a trait that decreases an organism's chance of survival.

• An advantageous trait is a characteristic that only affects an organism's color.

Fill in the blank: Define the term 'Environmental factors'.

• Environmental factors are external elements like climate, food, and predators that can affect an organism's survival.

• Environmental factors are the internal genetic codes that determine an organism's eye color.

• Environmental factors are the chemical reactions that occur inside an organism's cells.

• Environmental factors are the specific organs that help an organism to breathe underwater.
