Genetics Practice Quiz: Trivia Test!

Genetics is the study of how different traits such as hair color and texture, eye color, and disease risk are passed down or inherited from parent to offspring. Genetics helps to clarify what makes you unique as an individual. This quiz asks questions like who is considered the father of genetics, what does homozygous recessive genotype mean, and what happens to a chromosome during meiosis. Make sure you take your certificate after the quiz.
