Developing elite fruit cultivars typically requires long breeding cycles, especially in perennial woody species. This study uncovers how sexual reproduction of a fertile triploid loquat generates a ...

The human genome is organised in 46 chromosomes, where all but the x and y chromosomes in men are present in two copies. This means that a person with a faulty gene on one chromosome most often has a ...

Durham, N.C. – The first comprehensive survey of gene activity in the X chromosomes of women has revealed an unexpected level of variation among individuals, according to new work by researchers at ...

Highly challenging to sequence and long overlooked, the human Y chromosome's contributions to health and disease remain largely unknown. A new paper that presents, for the first time, the complete ...

Antibody-based therapies are used to treat numerous diseases, from cancer to rheumatic disorders and multiple sclerosis.

Females and males typically differ in many ways in their morphology, physiology and behaviour. How such sex differences, known as sexual dimorphism, evolve is a puzzle because females and males share ...

Prenatal genetic tests can detect sex chromosome aberrations, but what happens after—for families and children—is anything but clear. When Ollie’s mother, Katie, was nine weeks pregnant, her ...

No matter where you travel around the world, men in any given human population tend to be taller than women. Now researchers have uncovered a key genetic mechanism behind this anatomical contrast.
