Reproduction and Variation Flash Cards

What is variation within species?

• Differences in characteristics among individuals of the same species.

• Differences in characteristics between different species.

• The process by which species evolve over time.

• The ability of an organism to adapt to its environment.

What is genetic variation?

• The diversity in gene frequencies within a population.

• The process of natural selection acting on a population.

• The mutation rate of genes in a species.

• The total number of genes in an organism.

What is a key feature of asexual reproduction?

• It involves two parents and produces genetically diverse offspring.

• It involves only one parent and produces genetically identical offspring.

• It requires external fertilization to occur.

• It is a method of reproduction that only occurs in plants.

How does asexual reproduction affect genetic diversity?

• Asexual reproduction results in high genetic diversity as offspring are genetically varied.

• Asexual reproduction results in low genetic diversity as offspring are clones of the parent.

• Asexual reproduction has no effect on genetic diversity.

• Asexual reproduction increases genetic diversity through mutations.

What does sexual reproduction involve?

• The combination of genetic material from two parents.

• A single parent producing offspring.

• The cloning of an organism.

• The fusion of multiple gametes from the same parent.

How does sexual reproduction contribute to genetic diversity?

• It allows for asexual reproduction to occur.

• It combines genetic material from two parents, creating unique offspring.

• It results in identical offspring from a single parent.

• It eliminates genetic variation among offspring.

What are the two main types of reproduction?

• Asexual and sexual reproduction.

• Binary fission and budding.

• Pollination and fertilization.

• Mitosis and meiosis.

What is variation within populations?

• Differences in characteristics among individuals within a population.

• The process of natural selection acting on a population.

• The genetic makeup of a population remains constant over time.

• The migration of individuals into a population.

What is an example of a trait that can vary within a species?

• Fur color in animals

• Size of the species

• Habitat location

• Dietary preferences
