A chromosome-mapping study and literature synthesis found variation in the number, position and synteny of 5S and 35S rDNA ...

A cytogenetic study of seven species in the gourami family’s spiral egg clade found unusually low and variable chromosome ...

For decades, technical limitations and entrenched expectations shaped chromosome counts, illustrating how accepted scientific ideas can persist despite conflicting evidence.

Japanese researchers used CRISPR-Cas9 to remove the extra chromosome 21 from cells in a lab. It's a real breakthrough — but not a Down syndrome cure, and not a new 2026 treatment.

Single deletions may be asymptomatic, but 'multiple deletions lead to infertility'—Mouse study with comprehensive deletion of ...

The human Y chromosome, responsible for determining male sex, finally has gotten an end-to-end examination. The Y chromosome is the smallest of the human chromosomes. “In the old time, people thought ...

Results provide framework for uncovering regulatory variants in other X chromosome neurodevelopmental genes that may ...

Chromosomes are masters of organization. These long strings of DNA fold down into an ensemble of compact structures that keep needed parts of the genome accessible while tucking away those that aren't ...

For decades, the Y chromosome — one of the two human sex chromosomes — has been notoriously challenging for the genomics community to sequence due to the complexity of its structure. Now, this elusive ...
