Ch 11: Prentice Hall Biology Chapter 11: Introduction to Genetics

About This Chapter

The Introduction to Genetics chapter of this Prentice Hall Biology Textbook Companion Course helps students learn the essential biology lessons of genetics. Each of these simple and fun video lessons is about five minutes long and is sequenced to align with the Introduction to Genetics textbook chapter.

How it works:

  • Identify the lessons in Prentice Hall Biology's Introduction to Genetics 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, re-watch the videos until you've mastered the material or submit a question for one of our instructors.

Students will learn:

  • Properties of alleles
  • Mendel's first law
  • Mendel's second law
  • Codominance and incomplete dominance
  • Meiosis I and II
  • Chromosomal linkage and crossing over

Properties of Alleles

1. 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

2. 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

3. 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

4. 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.

Exceptions to Simple Dominance: Codominance and Incomplete Dominance

5. 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.

Meiosis: Comparison to Mitosis, Crossing Over & Process

6. Meiosis: Comparison to Mitosis, Crossing Over & Process

Welcome to meiosis, a realm of division doubled for reproduction untroubled. You'll get a preview of both divisions of meiosis and see what it takes to go from a diploid cell to a haploid gamete.

Meiosis I Stages: Prophase I, Metaphase I, Anaphase I & Telophase I

7. Meiosis I Stages: Prophase I, Metaphase I, Anaphase I & Telophase I

How does meiosis keep track of homologs and reduce the genome by half? Know these answers and more as we navigate the steps of meiosis I. This lesson will be tetradical!

Meiosis II: Definition, Stages & Comparison to Meiosis I

8. Meiosis II: Definition, Stages & Comparison to Meiosis I

Behold round two of meiotic cell division! You'll see how meiosis II keeps the genome intact and gives the final push to produce haploid gametes, which make the world go round.

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.

Homozygous Dominant: Definition & Example

10. Homozygous Dominant: Definition & Example

If a cat (or a person, or a pea plant) has two dominant alleles of a certain gene, we say it is homozygous dominant for that particular trait. Learn more about homozygous dominance with the help of some adorable cats!
