A baby’s genetic makeup is determined when the sperm meets the egg during fertilization. Typically, a full set of DNA is formed, which contains 23 pairs of chromosomes. Sometimes, extra chromosomes ...

Robertsonian chromosomes are large chromosomes that form when the long arm of a chromosome breaks and fuses with another chromosome. They are the most common type of chromosome rearrangement in humans ...

Robertsonian chromosomes (ROB) are a type of structurally variant chromosome that is created when two chromosomes fuse together to form an unusual bond. Found commonly in nature, these chromosomes are ...

The chromosome associated with male development, which is the last mysterious piece of the human genome, has been fully sequenced by a team of more than 100 researchers around the world, including ...

Sex chromosomes are chromosomes, or packages of DNA, that are found inside the nucleus of all of your cells. There are two different kinds: X and Y, which determine whether you’re biologically male ...

The Telomere-to-Telomere (T2T) consortium, co-led by UC Santa Cruz Genomics Institute Associate Director Karen Miga and National Institutes of Health Genomics Research Institute Senior Investigator ...

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 ...

Scientists have finally filled the gaps in the sequence of the human Y chromosome, 20 years after the first draft of its DNA code was published. The work reveals a complete catalog of the genes in the ...
