Parents at risk of passing on genetic disease to their children via mutations in the mother’s mitochondrial DNA could soon use a new IVF-based treatment involving healthy donor mitochondria.

The nomination of Judge Amy Coney Barrett has implications for how assisted reproductive technologies, which can prevent the transmission of disease from parents to child, are regulated.
A study claims the first humans lived in a wetland around what is now northern Botswana.
It’s likely our species doesn’t actually have a single origin.

Genetic analysis has traced the evolutionary footsteps of modern humans all the way back to a prehistoric wetland that spanned parts of modern-day Botswana, Namibia and Zimbabwe.
Where has this Zambian lion been?
Male lions are responsible for the movement of genes between prides. New research confirmed that the genes are traveling long distances – even though no one has been spotting the lions on the journey.
When it comes to reproduction, couple have more choices than ever before.
A ban on clinical trials involving gene editing rules out the controversial procedure done in China. But it also prevents procedures that could offer couples a chance for healthy children without genetic disorders.
Indigenous Australians must be involved in research around provenance and country. Here, representatives of the Willandra Aboriginal Elders visit the Griffith University ancient DNA laboratory.
Museums around the world hold remains of Aboriginal people that were often taken without permission and in the absence of accurate records. New DNA methods may help return these items to country.
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?
