Ch 18: CEOE Middle Level Science: Human Genetics

About This Chapter

The Human Genetics chapter of our CEOE Middle Level Science preparation course will show you what you need to know about human genetics to be successful on your exam. Our short video lessons and self-assessment quizzes give you solid review preparation for exam questions on these topics.

CEOE Middle Level Science: Human Genetics - Chapter Summary

This Human Genetics chapter will give you a comprehensive overview of human genetics and an in-depth look at genetic behavior and principles. Our lessons include Mendel's laws, chromosomal linkage and many other concepts. The Human Genetics chapter has lessons on:

  • An overview of genetics
  • Mendel's first, and second laws and their applications
  • Exceptions to simple dominance
  • Exceptions to independent assortment
  • Chromosomal linkage and crossing over
  • Genetics and human behavior
  • Genetic and environment interaction in influencing human development
  • Pedigree analysis in human development
  • Behavioral genetics

Our expert instructors will help you recall the basic concepts of genetics before gradually moving on to more complex principles. With our easy-to-navigate video system, accurate transcripts and self-assessment quizzes, you'll be better equipped to answer human genetics questions on the CEOE Middle Level Science exam.

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.

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.

Mendel's Dihybrid Cross Example: Practice & Ratio

5. Mendel's Dihybrid Cross Example: Practice & Ratio

Oh no! Twice the genes and sixteen genotypes - a dihybrid cross seems overwhelming to understand. Never fear though, Punnett squares will save the day!

Exceptions to Simple Dominance: Codominance and Incomplete Dominance

6. 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.

Exceptions to Independent Assortment: Sex-Linked and Sex-Limited Traits

7. Exceptions to Independent Assortment: Sex-Linked and Sex-Limited Traits

More men are color blind compared women. But often, not every brother, cousin or uncle in a family tree is color blind. Why not? How can genetics explain this seemingly complex inheritance pattern?

Crossing Over & Gene Linkage: Definition, Importance & Results

8. 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.

How Genetics Helps Us Understand Human Behavior

9. How Genetics Helps Us Understand Human Behavior

This lesson demonstrates how physical anthropologists use genetics to better understand the human experience. You'll learn how they combine their knowledge of both biology and the social sciences together to contribute to their field.

How Genetics and the Environment Interact in Human Development

10. How Genetics and the Environment Interact in Human Development

Everyone is different. But what makes a person unique? In this lesson, we'll examine the way genes and the environment affect who a person is, including looking at the nature vs. nurture debate and looking at how nature and nurture influence one another.

Pedigree Analysis in Human Genetics: Inheritance Patterns

11. Pedigree Analysis in Human Genetics: Inheritance Patterns

So you've learned what a pedigree is and how to read or even create one. Now you're ready to learn how to analyze a pedigree and figure out what kind of inheritance pattern a genetic condition follows!

Types of Studies in Behavioral Genetics: Twin, Family & Adoption

12. Types of Studies in Behavioral Genetics: Twin, Family & Adoption

Are you destined to inherit your mother's penchant for collecting old postcards or your father's constant worry that something bad is about to happen? Find out with this lesson, which delves into the world of genetic and environmental behaviors and personality traits.
