Ch 6: Understanding Plant Genetics

About This Chapter

Watch these short and engaging video lessons to study plant genetics. In addition to informative lessons, the chapter provides plenty of self-assessment quizzes that can help you practice answering plant genetics questions and prepare for upcoming exams.

Understanding Plant Genetics - Chapter Summary

These informative and engaging study resources provide a thorough overview of plant genetics. As you progress through the chapter, you'll outline fundamental principles, theories and laws in the field of genetics, such as Mendel's law of segregation and Bolveri and Sutton's chromosome theory of inheritance. You'll also define important genetic concepts, such as monohybrids, codominance, gene linkage and more.

This comprehensive chapter is designed to help you:

  • Explain the fundamentals of genetics
  • Define monohybrids and understand how they predict offspring characteristics
  • Summarize Mendel's law of segregation and law of independent assortment
  • Understand the concepts of codominance and incomplete dominance
  • Outline Bolveri and Sutton's chromosome theory of inheritance
  • Determine how linked genes can complicate genetics

Included in this chapter are several resources that are designed to supplement your studying experience and help you retain the information. Take the included self-assessment quizzes to practice answering questions related to plant genetics and print the lesson transcripts to study after watching video lessons. You can quickly navigate to specific topics on your course Dashboard and ask our expert science instructors any questions you may have. This chapter also allows you to study whenever you have free time and wherever you happen to be, whether you're at home, in a library or on-the-go.

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.

Monohybrid Cross: Definition & Example

2. Monohybrid Cross: Definition & Example

Some genetic characteristics are inherited in predictable patterns. In this lesson you will learn what monohybrids are and how to predict the kinds of characteristics that their offspring will show.

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.

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.

The Chromosome Theory of Inheritance: Segregation and Independent Assortment

6. The Chromosome Theory of Inheritance: Segregation and Independent Assortment

Mendel proposed the law of segregation and the law of independent assortment to explain the inheritance behind his pea plant traits. A hundred years later, Boveri and Sutton developed the chromosome theory of inheritance, which stated that chromosomes were responsible for the heredity Mendel observed. Learn about these men and their ideas in this lesson.

Linked Genes: Definition & Examples

7. Linked Genes: Definition & Examples

Gene linkage is one of those things that can turn even the simplest genetic question into a complex mess. This lesson will teach you what a linked gene is and take you through some solid examples.
