About This Chapter
MTEL Biology: Human Genetics - Chapter Summary
While you're reviewing the lessons in this chapter, you may come across some new subject matter that could show up on the MTEL Biology exam. Revisit information on the exceptions to simple dominance that include codominance and incomplete dominance in case there's a related question on the test. Whether it's behavioral genetics or another focus area, the content in this chapter will be fresh in your mind for the day of the test. As you go through the chapter, you'll see the following topics:
- Mendel's law of segregation and its application
- The law of independent assortment
- How genetics and the environment interact in human development
- Sex-linked and sex-limited traits
- Pedigree analysis in human genetics
- Chromosomal linkage and crossing over
You may watch these online lessons on any of your mobile devices. Learn at a pace that's comfortable for you as you get ready for the exam's questions on human genetics. During your review, you will see several questions in this chapter's practice quizzes that resemble potential test items.
MTEL Biology: Human Genetics Chapter Objectives
This chapter's aligned with the objectives of the Genetics, Evolution and Biodiversity subarea on the MTEL Biology exam. You'll be answering somewhere between 17 and 19 multiple-choice questions in this subarea. There's a possibility that genetics will be an area addressed in the open-response test items in the final subarea of the exam.
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.
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.
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.
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.
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!
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.
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?
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.
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.
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.
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!
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.
