Animals often give birth to litters of more than one offspring at a time. But are those babies twins?
Genes and environments almost always combine to influence our risk of diseases. Research in twins has helped us understand how.
Our study looked at both identical and non-identical sets of twins. We found that how sensitive you are is actually inherited genetically.
While identical twins are seen more as an accidental splitting of a single egg, there could be a good reason mothers produce non-identical twins from two separate eggs.
Interestingly, there are more non-identical twins in Australia now than there have been before. The number of twin pregnancies has grown over the past 30 years.
Semi-identical or sesquizygotic twins occur when two sperm fertilise one egg. A boy and a girl in Brisbane are only the second set of semi-identical twins known in the world.
New research is pinpointing how much genes influence the stability of educational achievement.
Our genes are important when it comes to aptitude for sleeping soundly.
A podcast on twins, including why stereotypes about their relationship are so damaging, and why they are so useful to scientists.
Can you blame bad teeth on your genes? Here’s why the answer is not as simple as you might think.
Research finds genes account for 50% of differences in social mobility.
Successfully separating conjoined twins is a complex operation that depends on how they are joined as well as the experience and skill of the surgical team.
The make-up of your gut bacteria will determine whether or not you put on weight.
Chronic pain often comes with other illnesses. Researchers have now shown that genetics can play a part in how likely you are to suffer.
Understanding how genes influence people’s behaviour doesn’t lead to fatalism.
It is an illness that runs in families – but there are other factors which go beyond inheritance.
Delivering twins is a balance between preventing pregnancy complications and the dangers of prematurity. New research suggests there is an optimum time.
Some students struggle because of biological constraints on learning. This can be overcome to an encouraging degree, but only with special and adequate resources.
Just because identical twins have exactly the same DNA, doesn’t mean they will have the same physical features.
A set of twins in Vietnam have been found to have different fathers.
