About This Chapter

Study this chapter's lessons if you'd like to prepare for the MTLE Life Science examination's questions on the concepts and principles of heredity. The chapter's text and video lessons are animated and fun. Short quizzes follow each one.

MTLE Life Science: Concepts and Principles of Heredity - Chapter Summary

Look to these text and video lessons if your MTLE Life Science testing session is approaching, and you need to brush up on your knowledge of heredity. In addition to reminding you of the differences between dominant and recessive traits, and explaining the process of genetic inheritance, the lessons will provide examples of co-dominance and incomplete dominance. Check out this chapter if you'd like to:

  • Explore the process of sexual reproduction
  • Define traits and review the different types
  • Utilize a Punnett square
  • Examine the statements of Mendel's Second Law
  • Identify dominant traits
  • Describe incomplete and co-dominance
  • Differentiate between sex-linked and polygenic inheritance

These text and video lessons are designed to be studied at your own pace. Benefit from the knowledge of experienced educators, many of whom have multiple relevant degrees. Master the above concepts and principles in an effort to prepare for the MTLE Life Science examination. Written transcripts and worksheets are included. Lesson summaries highlight the main points of the videos, and the self-assessment quizzes can determine how much you've remembered.

Sexual Reproduction: Inheriting Genes from Each Parent

1. 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.

What is a Trait? - Definition, Types & Examples

2. What is a Trait? - Definition, Types & Examples

This lesson introduces the concept of traits. In this lesson, learn about dominant and recessive traits, alleles and why some mice are white and others black. A quick summary and brief quiz follow the lesson.

Punnett Square: Definition & Example

3. Punnett Square: Definition & Example

This lesson will define what a Punnett square is and show several examples of how one can be used. It will also briefly describe patterns of inheritance.

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.

Dominant Trait: Definition & Example

5. Dominant Trait: Definition & Example

Can you roll the edges of your tongue towards the center? Do you have detached earlobes that hang free? Are your eyes brown? If you answered yes to any one of these, then you have a dominant trait. Learn what dominant traits are in this lesson.

Incomplete Dominance: Definition & Example

6. Incomplete Dominance: Definition & Example

Dominant/recessive inheritance is a common topic in genetics. Incomplete dominance is a naturally occurring phenomenon that may be present during the expression of this type of inheritance. This article describes incomplete dominance and goes over examples found in nature.

Codominance: Definition & Example

7. Codominance: Definition & Example

There are numerous factors that play a role in determining how an organism will look and act. In this lesson, you will learn about a genetic situation known as codominance.

The Influence of Sex-Linked and Polygenic Inheritance on Development

8. The Influence of Sex-Linked and Polygenic Inheritance on Development

What is sex-linked inheritance? What influence does it have on human development? What does it mean if a trait is polygenic? Learn the answers to these questions as this lesson explores this area of genetic inheritance.
