Heredity: Crash Course Biology
Hank and his brother John discuss heredity via the gross example of relative ear wax moistness.

Mendelian Genetics and Punnett Squares
For all of human history, we've been aware of heredity. Children look like their parents. But why? When Gregor Mendel pioneered the field of genetics, he began to try to answer that question, and now that we know about chromosomes, all...

Fundamentals of Genetics: Heredity
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...

TED-Ed: How Mendel's pea plants helped us understand genetics - Hortensia Jimenez Diaz
Each father and mother pass down traits to their children, who inherit combinations of their dominant or recessive alleles. But how do we know so much about genetics today? Hortensia Jimenez Diaz explains how studying pea plants revealed...
Amoeba Sisters
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...
TED-Ed
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,...

Heredity
Ear wax, either wet or dry, is inherited on chromosome 16. The narrator of a video about heredity uses ear wax to introduce the concepts of alleles, dominant and recessive traits, and heterozygous and homozygous genotypes.
Khan Academy
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...

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...
