This stems from the fact that animals contain pairs of chromosomes, one from the mother and one from the father. Humans have 23 pairs of chromosomes -- 23 from mom and 23 from dad -- for a total of 46 ...

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 ...

You may have learned in school that humans have 23 pairs of chromosomes: 22 “autosomes” and their partners, which contain pretty much the same genes and in the same order, plus one pair of sex ...

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 ...

Scientists have finally uncovered the exact DNA sequence where human chromosomes fuse to form Robertsonian chromosomes, a mystery that has puzzled researchers for over a century. Using advanced genome ...
