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.

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

2. 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?

Turner Syndrome and Trisomy X: Types of Sex Chromosome Aneuploidy

3. Turner Syndrome and Trisomy X: Types of Sex Chromosome Aneuploidy

Most females have two X chromosomes, which is what makes them women. But what happens when there are more or less than two X chromosomes in a woman's DNA? In this lesson, we'll explore Turner syndrome and Trisomy X.

Klinefelter and XYY Syndrome: Types of Sex Chromosome Aneuploidy

4. Klinefelter and XYY Syndrome: Types of Sex Chromosome Aneuploidy

Most boys and men have two sex chromosomes. But what happens when a male has more than two sex chromosomes? In this lesson, we'll explore two examples of male aneuploidy: Klinefelter Syndrome and XYY Syndrome.

What Is Huntington's Disease? - Symptoms, Genetic Cause & Treatment

5. What Is Huntington's Disease? - Symptoms, Genetic Cause & Treatment

In this lesson, you'll learn about a neurodegenerative disorder called Huntington's disease. You'll learn what a CAG repeat is, and how the number of these repeats can be used to predict whether or not a person will get Huntington's disease.

Genetic Disorders: Penetrance & Phenotypic Variability

6. Genetic Disorders: Penetrance & Phenotypic Variability

Did you know that sometimes a dominant human genetic condition will skip a generation in a family? It does happen, and some dominant genetic conditions will also have a wide range of phenotypes, sometimes even within the same family. Learn more in this lesson about phenotypic variability!

Parts of a Chromosome & Their Roles

7. Parts of a Chromosome & Their Roles

Learn all about chromosomes, including the different parts of a chromosome and the types of chromosomes in diploid organisms like humans. Learn the vocab used with chromosomes.

How is DNA Organized into Chromosomes? - Structure & Function

8. How is DNA Organized into Chromosomes? - Structure & Function

Explore the structure of chromosomes and see how DNA fits inside the nucleus of the cell. In this lesson, you'll learn about histones, chromatin and nucleosomes.

Natural Selection & Adaptation: Definition, Theory & Examples

9. Natural Selection & Adaptation: Definition, Theory & Examples

How does natural selection help shape the amazing types of animals we witness around us? In this lesson, we'll explore adaptations and what they can tell us about a species' past evolution.

Natural Selection: Definition, Types & Examples

10. Natural Selection: Definition, Types & Examples

We'll take a look at the types of natural selection that can occur. From flying hamsters to moths, you'll start to grasp the different paths organisms can take as they respond to their changing environments over time.

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

11. 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.

The Genetic Code: Influence of Mitosis, Meiosis & Crossing Over

12. The Genetic Code: Influence of Mitosis, Meiosis & Crossing Over

In this lesson, we will learn what the genetic code is and how it can be affected by mitosis, meiosis and crossing over. When mistakes are made and genes are altered, it can have a negative impact on human development.

Determination of Sex and Identical vs. Fraternal Twins

13. Determination of Sex and Identical vs. Fraternal Twins

Have you ever heard an old wives' tale about what determines whether a child will be a boy or a girl or what causes twins to be born? In this lesson, we will explore the biology behind these myths on how sex is determined and how twins are created.

The Influence of Single Gene-Pair Inheritance on Development

14. The Influence of Single Gene-Pair Inheritance on Development

What is single gene-pair inheritance? What influence does it have on human development? Learn the answers to these questions as we explore this area of genetic inheritance in this video lesson.

The Influence of Sex-Linked and Polygenic Inheritance on Development

15. The Influence of Sex-Linked and Polygenic Inheritance on Development

What is sex-linked inheritance? What influence does it have on human development? What does it mean if a trait is polygenic? Learn the answers to these questions as this lesson explores this area of genetic inheritance.

Genetic Abnormalities in Human Growth and Development

16. Genetic Abnormalities in Human Growth and Development

What are mutations and other chromosome abnormalities? How can these abnormalities affect human development? What are some common genetic disorders and their causes? Learn the answers to these questions in this lesson.

How Genetics and the Environment Interact in Human Development

17. How Genetics and the Environment Interact in Human Development
