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 single gene trait. This video serves as an introduction before exploring Punnett squares in our heredity series:

This video has a handout!

While this video only focuses on basic understanding of alleles and genes as well as the ability to taste- or not taste- PTC (phenylthiocarbamide), we encourage learning more! Here is a recommended reading that expands on the genetics involved in tasting PTC and includes some of the history in how it was discovered:

The Amoeba Sisters videos demystify science with humor and relevance. The videos center on Pinky's certification and experience in teaching science at the high school level. Pinky's teacher certification is in grades 4-8 science and 8-12 composite science (encompassing biology, chemistry, and physics). Amoeba Sisters videos only cover concepts that Pinky is certified to teach, and they focus on her specialty: secondary life science. For more information about The Amoeba Sisters, visit:


We cover the basics in biology concepts at the secondary level. If you are looking to discover more about biology and go into depth beyond these basics, our recommended reference is the FREE, peer reviewed, open source OpenStax biology textbook:

Mendelian Genetics

029 - Mendelian Genetics

Paul Andersen explains simple Mendelian genetics. He begins with a brief introduction of Gregor Mendel and his laws of segregation and independent assortment. He then presents a number of simple genetics problems along with their answers. He also explains how advances in genetic knowledge may lead to ethical and privacy concerns.

Genetics | Greatest Discoveries with Bill Nye

Genetics is the study of genes, genetic variation, and heredity in living organisms. It is generally considered a field of biology, but intersects frequently with many other life sciences and is strongly linked with the study of information systems.

Population Genetics: When Darwin Met Mendel - Crash Course Biology #18

Hank talks about population genetics, which helps to explain the evolution of populations over time by combing the principles of Mendel and Darwin, and by means of the Hardy-Weinberg equation.

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 Jiménez Díaz explains how studying pea plants revealed why you may have blue eyes.

‘Dark DNA’ Is the Latest Mystery in the World of Genetics… But What Is It?

Inside the Mysterious Dark Matter of the Human Genome

“When scientists sequenced the human genome a decade ago, it was somewhat like looking at a blueprint in a foreign language — everything was marked in its proper location, but no one could tell what it all meant.”

Dark Dna: The Missing Matter At The Heart Of Nature

“The discovery that some animals thrive despite hugely mutated DNA hidden in their genome is forcing us to rethink some basics of evolution.”

‘Dark Matter’ Dna Influences Brain Development

“A puzzle posed by segments of 'dark matter' in genomes — long, winding strands of DNA with no obvious functions — has teased scientists for more than a decade. Now, a team has finally solved the riddle.”

What are Haplogroups? Human Genetics Explained

Just what exactly are human haplogroups? Today let's discuss an integral part of human genetics, that I don't think I've explained in quite as much detail as I would like, including the emergence and spread of paternal and maternal haplogroups and their relation to race, ethnicity, language and other defining factors of modern human communities.

Please let me know your thoughts on the quirks of haplogroups and human genetics and which aspect of humanity best defines our groups and sub-groups. As always thanks for watching!

Genetic Recombination and Gene Mapping

In this video Paul Andersen explains how the frequency of recombination between linked genes can be used to determine the relative location of genes on a chromosome. Thomas Hunt Morgan and Alfred Strutevant used the fruit fly to develop a theory of chromosomal inheritance and discover crossing over.

Is Height Genetic?

↓↓↓ More info and sources below ↓↓↓

I’m tall. Most of the people in my family are tall. Does that mean my son will be tall? Turns out the inheritance of height is a lot more complicated than we thought. Scientists know that nature (genes) and nurture (environment) both play a role, but after more than a century of questions, we’re only just now starting to get some answers
