Sharing assignments in OpenClass
OpenClass is on a mission to improve & democratize education. Through our platform, educators can share assignments privately or with our entire community to improve accessibility of the best learning resources around the world.
Our assignments guide students through research-backed study sessions to reinforce learning. If this review is relevant to your teachings, feel free to add it to one of your classes!
Our format is simple and engaging: students are asked a retrieval question, then shown corrective feedback and a multiple-choice mastery question to assess their understanding of the material. Assignments adapt to unique student needs and continue to draw questions until a student has demonstrated mastery.
Explain how incomplete dominance differs from simple Mendelian inheritance in terms of phenotypic outcomes. Provide an example to illustrate your explanation.
Describe how codominance differs from simple Mendelian inheritance in terms of phenotypic outcomes. Provide an example to illustrate your explanation.
Compare and contrast the phenotypic outcomes of incomplete dominance and codominance using specific examples.
How would you distinguish between incomplete dominance and codominance in a genetic cross experiment?
Explain how the phenotypic ratios in the F2 generation differ between incomplete dominance and simple Mendelian inheritance.
Explain how the inheritance of human blood types demonstrates the concept of multiple alleles.
Describe how polygenic inheritance can result in a continuous range of phenotypes, using human skin color as an example.
How does the concept of epistasis differ from polygenic inheritance, and how can it affect phenotypic expression?
Explain how the concept of pleiotropy differs from polygenic inheritance and provide an example.
Discuss how environmental factors can influence the expression of polygenic traits, using human height as an example.
Explain why males are more likely to express X-linked recessive disorders such as color blindness and hemophilia compared to females.
Describe how a carrier female can pass on hemophilia to her offspring.
Analyze how the inheritance pattern of color blindness differs between males and females.
Discuss the potential genetic outcomes for the children of a color-blind male and a carrier female.
Explain how X-inactivation in females can affect the expression of X-linked disorders.
Discuss the potential genetic outcomes for the children of a color-blind male and a carrier female.
(Student response here)
The children of a color-blind male and a carrier female have the following potential genetic outcomes:
- Sons have a 50% chance of being color-blind and a 50% chance of having normal vision.
- Daughters have a 50% chance of being carriers and a 50% chance of being color-blind.
What is the probability that a daughter of a color-blind male and a carrier female will be color-blind?
