Genetics and Evolutionary Biology

1,123 Questions

Genetics and evolutionary biology explain how traits are passed from parents to offspring and how species change over time. Key concepts include genetic drift, inbreeding, and heredity. This topic is fundamental for the biology section of many competitive tests.

A Correct answer
Explanation

Gene-environment interaction refers to the combined effect of genetic and environmental factors in determining the risk of developing a disease.

Multiple choice

The term 'genetic susceptibility' refers to:

  1. The increased risk of developing a disease due to genetic factors

  2. The decreased risk of developing a disease due to genetic factors

  3. The ability of a genetic variant to cause a disease

  4. The mode of inheritance of a genetic trait

A Correct answer
Explanation

Genetic susceptibility refers to the increased risk of developing a disease due to the presence of specific genetic variants.

Multiple choice

Which of the following is NOT a factor that contributes to human diversity?

  1. Genetics

  2. Culture

  3. Environment

  4. All of the above
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

All of the above factors contribute to human diversity. Genetics, culture, and environment all play a role in shaping who we are. Our genes determine our physical characteristics and our susceptibility to certain diseases. Our culture influences our values, beliefs, and behaviors. Our environment influences our access to resources and opportunities.

Multiple choice

What is the process by which organisms better adapted to their environment are more likely to survive and reproduce, thus passing on their genes to the next generation?

  1. Natural Selection

  2. Artificial Selection

  3. Genetic Drift

  4. Mutation
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Natural selection is the process by which organisms better adapted to their environment are more likely to survive and reproduce, thus passing on their genes to the next generation.
