Ch 14: Campbell Biology Chapter 14: Mendel and the Gene Idea

About This Chapter

The Mendel and the Gene Idea chapter of this Campbell Biology Textbook Companion course helps students learn the essential biology lessons of Gregor Mendel's laws and genetics. Each of these simple and fun video lessons is about five minutes long and is sequenced to align with the Mendel and the Gene Idea textbook chapter.

How it works:

  • Identify the lessons in Campbell Biology's Mendel and the Gene Idea chapter with which you need help.
  • Find the corresponding video lessons within this companion course chapter.
  • Watch fun videos that cover the genetics topics you need to learn or review.
  • Complete the quizzes to test your understanding.
  • If you need additional help, rewatch the videos until you've mastered the material or submit a question for one of our instructors.

Students will learn:

  • Mendel's law of segregation and its applications
  • Mendel's law of independent assortment and its applications
  • Probability laws and Mendelian inheritance
  • Exceptions to simple dominance and independent assortment
  • Research methods in human genetics
  • How to create and read a pedigree
  • How to analyze pedigrees for inheritance patterns
  • Types and symptoms of genetic disorders

Mendel's First Law: The Law of Segregation

1. Mendel's First Law: The Law of Segregation

Breaking up is a hard thing to do, but homologous chromosomes always go their separate way. What effect does chromosome segregation have on genetics? We look once more to Adrian's flying hamsters for answers.

Application of Mendel's First Law

2. Application of Mendel's First Law

Hollywood Squares? No, it's Punnett Squares! Those wacky diagrams are a geneticist's best friend. See how they turn geneticists into soothsayers, predicting the genotypic and phenotypic future.

Mendel's Second Law: The Law of Independent Assortment

3. Mendel's Second Law: The Law of Independent Assortment

Understanding how Mendel's law of independent assortment describes inheritance of genes is as easy as flipping a coin. Grab a few coins, cue up the video and see how.

Mendel's Dihybrid Cross Example: Practice & Ratio

4. Mendel's Dihybrid Cross Example: Practice & Ratio

Oh no! Twice the genes and sixteen genotypes - a dihybrid cross seems overwhelming to understand. Never fear though, Punnett squares will save the day!

The Multiplication Rule & Mendelian Inheritance

5. The Multiplication Rule & Mendelian Inheritance

In this lesson, you're going to learn about basic concepts of probability and how they are applied to Mendelian inheritance with respect to the multiplication rule.

The Addition Rule Applied to Mendelian Inheritance

6. The Addition Rule Applied to Mendelian Inheritance

In this lesson, you're going to learn some basics concepts related to probability and how to apply the addition rule to problems related to Mendelian inheritance.

Using Probability to Solve Complex Genetics Problems

7. Using Probability to Solve Complex Genetics Problems

In this lesson, you're going to learn how to use Punnett squares and the multiplication rule to quickly solve complex genetic problems with respect to the law of independent assortment.

Exceptions to Simple Dominance: Codominance and Incomplete Dominance

8. Exceptions to Simple Dominance: Codominance and Incomplete Dominance

Have you ever wondered what it means if someone is a universal donor or acceptor of blood? See how genetic interactions play a key role in this trait.

Exceptions to Independent Assortment: Sex-Linked and Sex-Limited Traits

9. Exceptions to Independent Assortment: Sex-Linked and Sex-Limited Traits

More men are color blind compared women. But often, not every brother, cousin or uncle in a family tree is color blind. Why not? How can genetics explain this seemingly complex inheritance pattern?

Human Genetics Research Methods: Pedigrees and Population Genetics

10. Human Genetics Research Methods: Pedigrees and Population Genetics

Have you ever wondered how people study human genetics? Do you know what a pedigree or a complex disease is? In this lesson you'll learn about some of the techniques that human geneticists use and what pedigrees and complex diseases have to do with human genetics.

Pedigree Analysis in Human Genetics: Tutorial

11. Pedigree Analysis in Human Genetics: Tutorial

One of the oldest genetic techniques is pedigree analysis, and yet it is still used every day all around the world by doctors, geneticists, and genetic counselors. Building and reading a pedigree is actually fairly easy if you know what the symbols mean. In fact, it's so easy that you can learn how to do it in less than ten minutes if you watch this video!

Pedigree Analysis in Human Genetics: Inheritance Patterns

12. Pedigree Analysis in Human Genetics: Inheritance Patterns

So you've learned what a pedigree is and how to read or even create one. Now you're ready to learn how to analyze a pedigree and figure out what kind of inheritance pattern a genetic condition follows!

Types of Genetic Disorders: Definitions & Symptoms

13. Types of Genetic Disorders: Definitions & Symptoms

Cystic fibrosis, Huntington's disease, Tay-Sachs disease, sickle cell disease, Down syndrome, and cancer all have something in common. They are all genetic disorders, and we will discuss why they may occur and what problems they might cause.
