TED-Ed: How Mendel's Pea Plants Helped Us Understand Genetics
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.
TED-Ed: What Can DNA Tests Tell Us About Our Ancestry?
Two sisters take the same DNA test. The results show that one sister is 10% French, the other 0%. Both sisters share the same two parents, and therefore the same set of ancestors. So how can one be 10% more French than the other? Tests like these rely on our DNA to answer questions about our ancestry, but DNA actually can’t tell us everything. Prosanta Chakrabarty explores the accuracy of DNA tests.
TED-Ed: The Genes You Don't Get from Your Parents
Inside our cells, each of us has a second set of genes completely separate from our 23 pairs of chromosomes. And this isn’t just true for humans— it’s true of every animal, plant, and fungus on Earth. This second genome belongs to our mitochondria, an organelle inside our cells. So why are they so different from anything else in our bodies? Devin Shuman explores the purpose of mitochondrial DNA.
