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.

Properties of Alleles

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.

Mendel's First Law: The Law of Segregation

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.

Application of Mendel's First Law

4. 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.

Mendel's Second Law: The Law of Independent Assortment

5. 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.

Mendel's Dihybrid Cross Example: Practice & Ratio

6. 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!

Exceptions to Simple Dominance: Codominance and Incomplete Dominance

7. 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.

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

8. 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?

Crossing Over & Gene Linkage: Definition, Importance & Results

9. 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.

Human Genetics: Multifactorial Traits & Model Organisms

10. 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!

Allelic Frequency: Definition & Explanation

11. Allelic Frequency: Definition & Explanation

Allelic frequency is a calculation used in genetics. This lesson will recap some basic genetics and go over allelic frequency. Test your genetics and math skills with the quiz.

Genetic Modification: Definition, Advantages & Disadvantages

12. Genetic Modification: Definition, Advantages & Disadvantages

Genetic modification has allowed scientists to create some pretty neat things, like apples that don't brown and fish that glow. In this lesson, learn what genetic modification is and explore some of its advantages and disadvantages.

Incomplete Dominance: Definition & Example

13. Incomplete Dominance: Definition & Example

Dominant/recessive inheritance is a common topic in genetics. Incomplete dominance is a naturally occurring phenomenon that may be present during the expression of this type of inheritance. This article describes incomplete dominance and goes over examples found in nature.

P Generation: Definition & Offspring

14. P Generation: Definition & Offspring

The work of Gregor Mendel left us with important discoveries in the world of genetics. In this lesson, we'll discuss his ideas in regards to to the P generation in crosses.

Polygenic Inheritance: Definition & Examples

15. Polygenic Inheritance: Definition & Examples

In this lesson you will learn how traits like your height, weight, hair color, and skin pigmentation are determined by the complex interaction of several different genes in a process called polygenic inheritance.

Recombination: Definition & Process

16. Recombination: Definition & Process

Recombination is a nifty little way to mix up your DNA. In this lesson, you will learn about chromosomes, meiosis, and why recombination occurs. Test yourself afterwards with a quiz.

What Is Trisomy? - Definition & Symptoms

17. What Is Trisomy? - Definition & Symptoms

When a diploid organism has an extra copy of one of its chromosomes, it's called trisomy. In this lesson, find out what causes trisomy and its symptoms in humans.
