Higher yields, greater resilience to climatic changes or diseases—the demands on crop plants are constantly growing. To ...

Research shows synthetic chromosomes can be transferred to human cells with potential to improve viral resistance ...

An international research team has achieved the first complete sequencing of the human Y chromosome, which is closely linked to male development. This is the last of the human chromosomes to be fully ...

The Y chromosome in primates — including humans — is evolving much more rapidly than the X chromosome, new research on six primate species suggests. For instance, humans and chimpanzees share upwards ...

For any mammal, the loss of the Y chromosome should mean the loss of males and the demise of the species. So how the Amami spiny rat manages without a Y chromosome has puzzled biologists for decades.

Up to the present, at least 52 loci responsible for autosomal recessive non-syndromic hearing impairment (ARNSHI) have been published and 26 genes were identified ...

Scientists at the Sloan Kettering Institute have solved the puzzle of how small chromosomes ensure that they aren’t skipped over during meiosis, the process that makes sperm and egg. From avocado ...

In the 1960s, doctors counting the number of chromosomes in human white blood cells noticed a strange phenomenon. Frequently—and more frequently with age—the cells would be missing the Y chromosome.

Genes are segments of DNA (deoxyribonucleic acid) that are located inside every human cell. The DNA inside each cell is tightly coiled in structures called chromosomes. Each chromosome contains a ...

Abnormalities in the structure of chromosomes within someone’s genetic makeup are called structural chromosomal abnormalities. Robertsonian translocations are very rare structural chromosomal ...
