John Wilbanks: Let's pool our medical data
When you're getting medical treatment, or taking part in medical testing, privacy is important; strict laws limit what researchers can see and know about you. But what if your medical data could be used -- anonymously -- by anyone...

Alleles and Genes
Join the Amoeba Sisters as they discuss the terms "gene" and "allele" in context of a gene involved in PTC (phenylthiocarbamide) taste sensitivity. Note: as mentioned throughout video, the ability to taste PTC may be more complex than a...

Introduction to Genetic Diagrams for Single Gene Inheritance
This video provides an explanation of genetic diagrams and their use in studying single gene inheritance, also known as monohybrid inheritance. Using the example of superpowers inherited through a single gene, the video demonstrates how...

Genetics | Dihybrid Cross (Example 2)
A second example of a dihybrid cross in which the paternal AaBb gamete is crossed with the maternal AaBb gamete (both parents are doubly heterozygotes for genes A & B)

Fundamentals of Genetics: Hybrid Cross
In this program Mendel's work is explored in greater detail by using probability to make predictions of the inheritance of specific traits. The use of the Punnett Square is illustrated through easy-to-understand animations. Other...

Codominance
In this video we are now going to look at codominance. You need to understand the difference between genotype and phenotype. The genotype is the set of genes. The phenotype are the physical characteristics that are coded for by the...

How Mendel's Pea Plants Helped Us Understand Genetics
A brief animation introduces heredity to your beginning biologists. They will meet Gregor Mendel's green and yellow peas, dominant and recessive traits, homozygous and heterozygous alleles, and Punnett squares. In this cartoon animation,...

Mendelian Genetics and Inheritance
Introduce your biologists to Gregor Mendel, the man responsible for Mendelian genetics. The resource explains the experiment that made him famous and sparked interest in genetics everywhere. Also take a closer look at Huntington's...

Hardy-Weinberg Principle
After learning to calculate probabilities for single examples of genetic crosses in a previous lecture, students are exposed to the concept that allele and genotype frequencies in a population remain in constant equilibrium. A reasonable...

Introduction to Heredity
Young scientists generally love to learn how certain traits can be explained by a direct combination of alleles from their parents. Here, they can examine how a phenotype is often expressed when one allele is recessive and the other is...

Punnett Square Fun, Biomolecules, MCAT
The topics in the previous video about dominant and recessive traits are continued here as Sal Khan explains incomplete dominance, the randomness of genotypes and phenotypes, and covers how to calculate probabilities using Punnett...

Alleles and Genes
How do organisms end up with such a wide variety of traits? It's in their genes! Kick off your inherited traits lesson using a brief video that covers alleles and genes. The narrator describes heterozygous and homozygous genotypes, how...

Codominance
Some alleles share codominance rather than dominant or recessive. The video explains how codominance is determined and what it looks like in animals. Part of the Fuse School Genetics series, it relates the topic to human blood types and...
