About This Chapter

The Mendelian concepts chapter of this MCAT Help and Review course is the simplest way to master genetics. This chapter uses simple and fun videos that are about five minutes long, plus lesson quizzes and a chapter exam to ensure students learn all the essential Mendelian concepts.

Who's it for?

Anyone who needs help learning or mastering MCAT material will benefit from taking this course. You will be able to grasp the subject matter faster, retain critical knowledge longer and earn higher scores. You're in the right place if you:

  • Have fallen behind in understanding the applications of Mendel's first and second laws
  • Need an efficient way to learn about Mendelian concepts
  • Learn best with engaging auditory and visual tools
  • Struggle with learning disabilities or learning differences, including autism and ADHD
  • Experience difficulty understanding your teachers
  • Missed class time and need to catch up
  • Can't access extra MCAT review resources at school

How it works:

  • Start at the beginning, or identify the topics that you need help with.

  • Study With Flexibility: Watch videos on any web-ready device.

Students will review:

In this chapter, you'll learn the answer to questions including:

  • What are the properties of alleles?
  • What are the laws of segregation and independent assortment?
  • How are codominance and incomplete dominance different from simple dominance?
  • What are some examples of sex-linked and sex-limited traits?
  • What causes wild-type and mutant alleles?
  • How is pedigree analysis performed in human genetics?
  • What are some human genetics research methods?

Genetics: Heredity, Traits & Chromosomes

1. Genetics: Heredity, Traits & Chromosomes

We view manipulation of genes in our crops and livestock as a recent development. Yet, man has been manipulating the genetic makeup of his food for thousands of years through cultivation and breeding. This lesson will begin to help you understand how genetics works.

Properties of Alleles

2. Properties of Alleles

What is a dominant phenotype and how will it affect Adrian's flying hamster research? Tune in as he studies homozygous and heterozygous genotypes and the phenotypes they produce.

Mendel's First Law: The Law of Segregation

3. 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

4. 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

5. 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

6. 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!

Exceptions to Simple Dominance: Codominance and Incomplete Dominance

7. 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

8. 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?

Pedigree Analysis in Human Genetics: Inheritance Patterns

9. 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!

Pedigree Analysis in Human Genetics: Tutorial

10. 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!

Human Genetics Research Methods: Pedigrees and Population Genetics

11. 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.

Dominant vs. Recessive Alleles

12. Dominant vs. Recessive Alleles

Watch this video lesson to learn about Mendelian inheritance. It explains why we have the eye color that we have as well as the reason that some people have certain disorders and others don't.

Genetic Implications of the Gene Pool

13. Genetic Implications of the Gene Pool

This lesson explores the relationship between the gene pool, genetic diversity, as well as factors such as population size and inbreeding and their effect on the gene pool.
