About This Chapter
ILTS Biology: Genetics & Heredity - Chapter Summary
Find out more about genetics and the principles of heredity as you prepare for the ILTS Biology exam. Our entertaining lessons and self-assessment quizzes let you review information on topics including:
- Fundamentals of genetics
- Mendel's laws of heredity
- Codominance and incomplete dominance
- Sex linked and sex limited traits
- Chromosomal linkage
- Model organisms and human genetics
- Research methods for human genetics
You can study our lessons as your schedule allows, using a computer, smartphone or tablet to review the information no matter where you are. We offer several ways to help you succeed on the ILTS Biology exam, including written lesson transcripts with key terms highlighted and printable quizzes that let you study even when you don't have Internet access.
ILTS Biology: Genetics & Heredity Chapter Objectives
Illinois makes passing the ILTS Biology exam one of the requirements for obtaining certification to teach the subject. This exam has 125 multiple-choice questions covering a range of topics divided into six subareas. Questions on the material explored in this chapter are found in the exam's subarea on Cell Biology, Heredity and Evolution.
You can get experience answering these types of questions through the quizzes that follow each of our lessons. These quizzes allow you to evaluate your knowledge. The answer key includes links back to the lesson videos. If you answer a question incorrectly, you can quickly pop back to the pertinent section of the lesson and review the teaching on that topic.
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. Properties of Alleles
What is a dominant phenotype and how will it affect Adrian's flying hamster research? Tune in as he studies homozygous and heterozygous genotypes and the phenotypes they produce.
3. Mendel's First Law & Its Application
Genetics is a fascinating and confusing world. This lesson will delve into Gregor Mendel's First Law, or the Law of Segregation, explaining what it means and how you can use it.
4. Mendel's Second Law & Its Application
In this lesson, we'll explore how genes can assort independently according to Mendel's second law. We'll also use Punnett squares to see whether or not genes are linked and how this relates to research.
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.
6. 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?
7. 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.
8. Human Genetics: Multifactorial Traits & Model Organisms
How do we study human genetics when most traits arise from multiple genes? It's certainly more complicated that drawing a simple Punnett square. Never fear, for model organisms are here!
9. Human Genetics Research Methods: Pedigrees and Population Genetics
Have you ever wondered how people study human genetics? Do you know what a pedigree or a complex disease is? In this lesson you'll learn about some of the techniques that human geneticists use and what pedigrees and complex diseases have to do with human genetics.
