Ch 11: STAAR Science - Grade 8: Genetics

About This Chapter

Students can use the lessons in this chapter to refresh their understanding of genetics, in order to feel prepared for these kinds of questions on the STAAR Science - Grade 8 exam.

STAAR Science - Grade 8: Genetics - Chapter Summary

The lessons in this chapter will delve into important information about genes, heredity and evolution to help students study for the STAAR Science - Grade 8 exam. With these lessons, students will explore:

  • The definition, structure and function of genes and genetic material
  • Inheriting genes through sexual reproduction
  • Types of asexual reproduction
  • Natural selection and the process of adaption
  • Artificial selection and its impact on evolution
  • Speciation and how new species are formed

Our instructors have developed these lessons to help students easily absorb and retain the information being reviewed. You'll find engaging video and text lessons to illustrate the material. Students can take a self-assessment quiz after each lesson to apply what they've learned. At the end of the chapter, a cumulative exam is available for students to test their knowledge of the topics.

What Is a Gene? - Definition & Structure

1. What Is a Gene? - Definition & Structure

Genes are little codes found in our cells that make up who we are. This lesson covers where genes are located, how we get our genes, and the functions of genes.

Genetic Material: Definition, Structure & Function

2. 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.

Sexual Reproduction: Inheriting Genes from Each Parent

3. Sexual Reproduction: Inheriting Genes from Each Parent

Organisms reproduce in order to make offspring. With sexual reproduction the offspring get a combination of the genetic material from two parents. Learn how the male and female reproductive cells, called gametes, come together during fertilization.

Types of Asexual Reproduction

4. Types of Asexual Reproduction

If an organism comes from a single parent, then it reproduced asexually. This results in genetically identical offspring. Learn about different types of asexual reproduction, such as binary fission, fragmentation, budding and vegetative propagation.

Natural Selection & Adaptation: Definition, Theory & Examples

5. Natural Selection & Adaptation: Definition, Theory & Examples

How does natural selection help shape the amazing types of animals we witness around us? In this lesson, we'll explore adaptations and what they can tell us about a species' past evolution.

Artificial Selection in Evolution

6. Artificial Selection in Evolution

Humans have been selectively breeding for desirable traits in plants and animals for a long time. This artificial selection allows for a lot of control in the breeding process but can also lead to unintended mutations within a population of organisms.

Speciation: Definition, Examples & Role in Evolution

7. Speciation: Definition, Examples & Role in Evolution

Can you believe that over two million species have been identified on Earth? Have you ever wondered how so many species formed on Earth? Learn more about how new species form and test your knowledge with a quiz.
