About This Chapter
Fundamentals of Genetics - Chapter Summary
Genetics could be loosely described as the study of why living things are the way they are. In this chapter, you can review the basics of Mendel's laws, learn more about what alleles are, and gain an overview of genetics in general.
Each of these short lessons is followed by an equally brief quiz, while the longer chapter test will allow you to measure your overall progress. Our highly qualified instructors and subject matter experts can provide you with whatever assistance you might need, and the brightly written and informative content keeps your interest engaged. The convenient online format and easy access allows you complete freedom to schedule your work sessions whenever you like, and the Dashboard keeps you organized. These lessons cover the following material:
- Explanation and definition of genetics
- Structure, composition and properties of alleles
- Mendel's laws of segregation and independent assortment
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: 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.
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.
