Gregor Mendel's principles of inheritance form the cornerstone of modern genetics. So just what are they? When looking at the figure, notice that for each F 1 plant, the self-fertilization ...

Science is rarely straightforward. Many times, scientists embark on a study looking for evidence for a particular hypothesis, ...

Some characteristics are controlled by a single gene, such as fur in animals and red-green colour blindness in humans. Each gene might have different forms, and these are called alleles.

This might result in a change in phenotype or it might appear hidden, and be unnoticed. Alternatively, they might result in a serious consequence, such as genetic disease like cystic fibrosis.

DNA is a mosaic of genetic fragments passed down through generations, but its clarity diminishes over time. While modern testing can trace ancestry through shared markers, the depth of this insight ...

Thus, this disorder shows multifactorial inheritance, because both genetic and environmental factors trigger its onset. But what are the distinguishing factors of this and other multifactorial ...

Genetic testing is available to check for mutations ... even if their eye color isn’t blue. “For dominant inheritance, a ...

But these corals do pass on such mutations, according to a new study published in Science Advances yesterday (August 31). The finding points to a new source of genetic variation in coral that may ...

A new approach reveals genetic interactions that contribute to heart defects. Scientists at the Icahn School of Medicine at ...

Scientists at the Icahn School of Medicine at Mount Sinai have uncovered new genetic interactions that may contribute ...

The diagnosis of Duchenne muscular dystrophy, a genetic condition, impacts both the person affected and their family.

If neither parent is found to have signs of NF1, the child’s disorder is most likely the result of a spontaneous, or new, mutation. Genetic testing is also currently available to confirm the presence ...
