Ch 11: Washington EOC Biology Grade 10: Fertilization & Offspring Variation

About This Chapter

Use these video lessons to learn some important facts about fertilization and offspring variation. These facts might be included on the Washington EOC grade 10 biology exam.

Washington EOC Biology Grade 10: Fertilization & Offspring Variation - Chapter Summary

If you are going to take the Washington End-of-Course (EOC) Exam on grade 10 biology, you will encounter questions on the subject of fertilization and offspring variation. You can study this subject by watching the video lessons contained within this chapter. Some of the topics you'll learn about in the lessons are:

  • Overview of meiosis
  • Nondisjunction and aneuploidy
  • The promotion of genetic variation by meiosis and fertilization
  • Zygote formation
  • Genotypes
  • Mendel's First Law and Second Law
  • The genetic code

Once you've completed the lessons, you can test your understanding of the topics by answering the questions in the practice quizzes. The chapter as a whole will serve as an essential study guide for the Washington EOC Biology Grade 10 exam.

Meiosis: Comparison to Mitosis, Crossing Over & Process

1. 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

2. 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

3. 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.

Nondisjunction & Aneuploidy: Definition & Examples

4. Nondisjunction & Aneuploidy: Definition & Examples

Learn why proper chromosome segregation is essential during meiosis. We'll see how having an extra chromosome can lead to Down Syndrome and also examine the consequences of having too few chromosomes. Disruptions to the delicate balance of cell division can have far-reaching effects.

How Meiosis & Fertilization Promote Genetic Variation

5. How Meiosis & Fertilization Promote Genetic Variation

Individuals are different because of their genetic variation. Even two siblings who come from the same parents have different genetic make-ups. This variation comes from both meiosis and fertilization, which are components of sexual reproduction.

Fertilization and Zygote Formation: Definition and Processes

6. Fertilization and Zygote Formation: Definition and Processes

Follow the male's sperm and the female's egg on their way to meet each other in this lesson that takes you through the process of fertilization in humans. Learn about the obstacles the sperm must get through before it can fertilize the egg.

What are Genotypes? - Definition & Examples

7. What are Genotypes? - Definition & Examples

In this lesson, you will learn about what genotypes are, where they come from and how they play a major role in determining how your body works and what you look like.

Properties of Alleles

8. 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

9. 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.

Mendel's Second Law: The Law of Independent Assortment

10. 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.

The Genetic Code: Influence of Mitosis, Meiosis & Crossing Over

11. The Genetic Code: Influence of Mitosis, Meiosis & Crossing Over

In this lesson, we will learn what the genetic code is and how it can be affected by mitosis, meiosis and crossing over. When mistakes are made and genes are altered, it can have a negative impact on human development.
