Genetic Engineering Will Change Everything Forever – CRISPR

Designer babies, the end of diseases, genetically modified humans that never age. Outrageous things that used to be science fiction are suddenly becoming reality. The only thing we know for sure is that things will change irreversibly.

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:

Is Height Genetic?

Check out ReInventors:
Make watching our videos a habit and SUBSCRIBE! ►►
↓↓↓ 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

How Mendel's pea plants helped us understand genetics - Hortensia Jiménez Díaz

View full lesson:

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.

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.”

Introduction to Genetics

This HD dramatic video choreographed to powerful music introduces the viewer/student to the science of Genetics and Inheritance. It is designed as a motivational trailer to be shown in classrooms by Biology teachers in middle school, high school and college as a visual Introduction to the history and science of Genetics, Heredity and Biotechnology.

Please rate this video and feel free to comment. If you like it, please help me spread the word by posting links on your media websites. The more students who can enjoy these dramatic videos, the better!

To view all of my videos in Biology, Earth Science, and Astronomy, subscribe to my channel at: I will be releasing new ones periodically.

I wish to thank all the quality video and music producers whose postings enabled me to assemble this video for educational use. To best enjoy this video, turn up your speakers. The music is very powerful and dramatic!

I can customize this video to add your name or school name at the end credits, for a very modest fee. If interested, email me at fsgregs@comcast.net

Until recently, you were able to download my videos for free from my other video storage site (vimeo.com). Recently, however, they began charging a significant membership fee to enable that feature, so downloading from there is no longer available. However, you can search for and obtain free download addons for your browser that will allow you to download my videos from either YouTube or Vimeo.

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.

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.

Sometimes trail blazers of science aren't famous like Darwin or Pasteur. Sometimes they're humble Abbots, just growing peas in the back of their Abbey. This is the story of Gregor Mendel and how his work was done, lost, then found again.

New Discoveries in Population Genetics - with Enrico Coen

Every species seems beautifully adapted to its way of life, so why do species ever change? Enrico Coen gives the 2017 JSB Haldane Lecture.
Subscribe for regular science videos:

Watch the Q&A here:

Enrico Coen discusses how studying the snapdragon flower and its wild relatives is providing fresh answers to questions about adaptive change and population transformation. He will show how genes and environment interact to drive populations to explore new evolutionary paths.

Enrico Coen is a biologist who studies the mechanisms used by plants to create complex and varied flower structures. Enrico combines molecular, genetic and imaging studies with population and ecological models and computational analysis to understand flower development.

This talk was recorded in the Royal Institution on 21 November 2017.
