About This Chapter
NYSTCE Biology: Classical, Molecular and Population Genetics - Chapter Summary
Take the opportunity to strengthen your knowledge of Mendel's laws and the process of simple dominance through this chapter, which includes illustrated text and video lessons. While you prepare for the NYSTCE Biology examination's questions, you can further examine the principles of genetics, chromosomal linkage and research methods in human genetics. Have a look at these online lessons in order to:
- Explain the applications of Mendel's first and second laws
- Explore the fundamentals of genetics and the properties of alleles
- Understand co-dominance and incomplete dominance
- Discuss the factors that go into sex determination
- Examine the implications of crossing over
- Learn more about model organisms and population genetics
Each of the short lessons highlights a genetics-related topic. Through a combination of teacher instruction and self-paced study, you can become more prepared for the NYSTCE Biology examination. Watch the narrated videos, pause and re-watch the lessons or refer to the written transcripts at any time. You'll also find tabs for accessing quizzes and related courses.
NYSTCE Biology: Classical, Molecular and Population Genetics Chapter Objectives
You'll be required to complete the NYSTCE Biology examination in four hours or less. There are seven subareas on the paper-based examination, which includes 90 multiple-choice questions and one constructed-response assignment. Showcase your expertise in classical, molecular and population genetics during the Genetics and Evolution subarea, which makes up 15% of the overall examination. Some questions on this subarea could address dominance and incomplete dominance as well as independent assortment and the principles of heredity. Apply your knowledge as you seek a biology teaching certification in New York State.
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.
