When a woman becomes pregnant, the outcome of that pregnancy depends on many things—including a crucial event that happened ...

Researchers are now exploring how different types of repetitive DNA create genome instability and structurally variant chromosomes.

Kansas City scientists have made a "landmark" discovery that offers new insights into some cases of infertility, miscarriage ...

In about one out of every 800 people, two chromosomes fuse together to form an unusual bond. These are known as Robertsonian chromosomes. It's a mystery that has long stumped scientists.

In a recent study, researchers sequenced Robertsonian chromosomes completely, telomere to telomere, for the first time. 1 They discovered a common DNA breakpoint that leads to the formation of ...

Every new life begins after a genetic shuffle. When organisms make eggs or sperm, maternal and paternal chromosomes pair up and swap pieces of DNA in ...

Most don’t learn they carry this genetic anomaly unless they experience reproductive problems and seek testing. Robertsonians — commonly abbreviated as ROBs — are the stuff of genetics textbooks.

Researchers have uncovered a previously unknown mechanism that safeguards the chromosome ends from being mistakenly repaired by the cell. While DNA repair is vital for survival, attempts to repair the ...

The Atlas blue butterfly has 229 chromosome pairs, the most of any animal, and its DNA may reveal insights into evolution and ...

Karyotype analysis plays a central role in cytogenetics, helping to reveal evolutionary processes and species relationships.

Scientists are trying to sequence the DNA of Leonardo da Vinci to identify if the remains at his interment site really are ...
