Ch 14: AP Biology - Genetics and Heredity: Help and Review

About This Chapter

The Genetics and Heredity chapter of this AP Biology Help and Review course is the simplest way to master genetics and heredity. This chapter uses simple and fun videos that are about five minutes long, plus lesson quizzes and a chapter exam to ensure students learn the essentials of genetics and heredity.

Who's it for?

Anyone who needs help learning or mastering AP Biology material will benefit from taking this course. There is no faster or easier way to learn AP Biology. Among those who would benefit are:

  • Students who have fallen behind in understanding the laws and theories associated with genetics and heredity
  • Students who struggle with learning disabilities or learning differences, including autism and ADHD
  • Students who prefer multiple ways of learning science (visual or auditory)
  • Students who have missed class time and need to catch up
  • Students who need an efficient way to learn about genetics and heredity
  • Students who struggle to understand their teachers
  • Students who attend schools without extra science learning resources

How it works:

  • Find videos in our course that cover what you need to learn or review.
  • Press play and watch the video lesson.
  • Refer to the video transcripts to reinforce your learning.
  • Test your understanding of each lesson with short quizzes.
  • Verify you're ready by completing the genetics and heredity chapter exam.

Why it works:

  • Study Efficiently: Skip what you know, review what you don't.
  • Retain What You Learn: Engaging animations and real-life examples make topics easy to grasp.
  • Be Ready on Test Day: Use the genetics and heredity chapter exam to be prepared.
  • Get Extra Support: Ask our subject-matter experts any genetics and heredity question. They're here to help!
  • Study With Flexibility: Watch videos on any web-ready device.

Students will review:

This chapter helps students review the concepts in a genetics and heredity unit of a standard AP Biology course. Topics covered include:

  • Characteristics of alleles
  • Mendel's first and second laws
  • Independent assortment
  • Simple dominance
  • Chromosomal linkage
  • Human genetics and model organisms

14 Lessons in Chapter 14: AP Biology - Genetics and Heredity: Help and Review
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?

Crossing Over & Gene Linkage: Definition, Importance & Results

9. Crossing Over & Gene Linkage: Definition, Importance & Results

During this latest development of his flying hamster experiments, Adrian must learn about linked genes and recombinant chromosomes to unlock the mystery of the fire-breathing hamster. In this lesson, you'll look at another exception to Mendel's law of independent assortment.

Human Genetics: Multifactorial Traits & Model Organisms

10. Human Genetics: Multifactorial Traits & Model Organisms

How do we study human genetics when most traits arise from multiple genes? It's certainly more complicated that drawing a simple Punnett square. Never fear, for model organisms are here!

Genetic Algorithms: Examples & Purpose

11. Genetic Algorithms: Examples & Purpose

This lesson explains what genetic algorithms are and gives examples of them. Both molecular biology and computer science are used to discuss a fairly new field called bioinformatics, which utilizes both.

Dihybrid Cross: Definition & Example

12. Dihybrid Cross: Definition & Example

In this lesson, learn what a dihybrid cross is and see an example. Also, find out about phenotypic ratio and how it's the same for each dihybrid cross. After the lesson, test your knowledge with a quiz.

Genetic Material: Definition, Structure & Function

13. Genetic Material: Definition, Structure & Function

Genetic material, also known as deoxyribonucleic acid (DNA) and Ribonucleic acid (RNA), plays a fundamental role in the composition of living organisms. Learn more about the definition, structure, and function, then test your understanding with a quiz.

Proband: Definition & Overview

14. Proband: Definition & Overview

What - or who - is a proband? Read this lesson to find out what a proband is and why a proband is important for treating genetic disorders. Then take the quiz to test what you've learned.
