We previously thought mitochondrial DNA could only be passed on by mothers.

The concept of three-parent babies defies what we learned in health class. But how and when is the third parent involved? At what stage? Jennifer Barfield gives us an update on the birds and the bees.
Lake Mungo and the surrounding Willandra Lakes of NSW were established around 150,000 years ago.
New techniques for genetic analysis are helping us build more detailed and accurate stories about the ancient histories of the first Australians.
Families have secrets - and sometimes we don’t know our complete genetic histories.
Ancestry and identity are not the same thing. A scientist tells the story of what happened when he sent his DNA to an ancestry company.
When a cell divides, mitochondria are randomly allotted to the resulting new cells.

The genes in our cells' mitochondria are passed on in a different way than the vast majority of our DNA. New studies shed light on how the unique process isn't derailed by mutations.
Is this how we got the sperm and the egg?
An ancient sexual conflict over mitochondrial inheritance may be responsible for the evolution of the two sexes as we know them.
Mitochondria live inside our cells but have a different genome. Here’s why.
To explain why we have a mitochondria, we have to go back about two billion years to a time when none of the complexity of life as we see it today existed.
Forensic techniques are getting more sophisticated.

Genetic evidence has become a critical aspect of modern criminal investigations. What are the methods and approaches used in present-day DNA forensics?
Fish leave bits of DNA behind that researchers can collect.

Animals shed bits of DNA as they go about their lives. A new study of the Hudson River estuary tracked spring migration of ocean fish by collecting water samples and seeing whose DNA was present when.
Human oocyte in vitro fertilization.
Medical tourism for assisted reproductive technologies raises a host of legal and ethical questions.
Scientists found that malaria parasites resistant to antimalarial Atovaquone cannot survive inside their mosquito host.
Resistance to a commonly used antimalarial medication, Atovaquone, can’t spread to the general human population, a new research found.
To whom is she more closely related?
How many times do people make the comment about which parent a child takes after. So what does genetics say?

Genomes from the 500-year-old remains of King Richard III and a direct living descendant are to be sequenced by scientists…
Three-parent IVF is about allowing women who carry genetic diseases in their mitochondria to avoid passing them on to their children.
Far from creating designer babies, three-parent IVF is about allowing women who carry genetic diseases in their mitochondria to avoid passing them on to their children. The process involves replacing the…
Let’s start humanity, genetically speaking.
All scientific evidence points to the fact that, if you go far enough back, all life on Earth is related through common ancestry…
Looks like a modern human, but isn’t. Evolution just got more complicated.
The DNA of Albert Perry may change the story of human origins. Perry was an African-American born into slavery in South Carolina. An analysis of the DNA of his descendants produced results that came as…
Mitochondrial genes are inherited from our mothers’ eggs and passed on through her daughters to subsequent generations.
The UK government has announced its intention to draft proposals allowing carriers of mitochondrial disease to have babies using a controversial IVF treatment that’s currently prohibited. The procedure…
The skeleton of Richard III was discovered beneath a car park in Leicester, and identified using the DNA of his descendants.
In the past few days news has come to light of the confirmation that skeletal remains discovered in an excavated site of a Leicester car park are indeed that of the famous English king Richard III. But…
Research has found that mitochondria, subcellular structures in the brain responsible for metabolising energy, can no longer…
Mutations in the DNA of mitochondria appear to help explain why women live, on average, longer than men. Genetic variations…
