14 Questions
What is the primary cause of genetic variation within a species?
Genetic mutations
Which of the following is NOT a factor that contributes to genetic variation?
Selective breeding
How do mating patterns affect genetic variation?
Outbreeding increases variation, while inbreeding decreases it
Which of the following is an example of phenotypic variation?
Skin color
How does the distribution of individuals within a species affect genetic variation?
Widely distributed individuals can either increase or decrease genetic variation, depending on other factors
Which of the following is an example of genetic variation?
Blood type
What is the primary effect of genetic drift on genetic variation?
Genetic drift decreases genetic variation
Which of the following is NOT a cause of genetic variation within a species?
Natural selection
How do migrating individuals affect the genetic makeup of a population?
They introduce new genetic variants into the population.
Which of the following is an example of genotypic variation?
Blood type
How does crossing over during meiosis contribute to genetic variation?
It shuffles the genetic material between homologous chromosomes.
What is the primary effect of genetic drift on genetic variation?
It decreases genetic variation within a population.
Which of the following is an example of both genetic and environmental variation?
Weight
Which type of genetic variation is responsible for differences in observable traits, such as appearance and behavior?
Phenotypic variation
Explore the concept of genetic variation, which refers to the differences caused by one's genes or the environment. Learn how genetic variation influences observable traits like appearance, smell, and more, and understand how it can result in phenotypic and genotypic variations. Discover examples of genetic variations such as blood type and eye color.
