Genetic variation is the ultimate fuel for evolution, says Utah State University evolutionary geneticist Zachariah Gompert. But, over centuries, that fuel reservoir gets depleted in the course of ...

Advancements in genome sequencing have challenged the long-standing belief that the position of the centromere in the chromosome is fixed. Researchers from Okayama University, Japan, have analyzed ...

How do living things evolve? What is the myriad of processes by which generic variations in a population affect organisms' survival and allow reproduction in an ever-changing environment? Why do these ...

Understanding the material basis of adaptive evolution has been a central goal in biology dating back to at least the time of Darwin. One focus of current debates is whether adaptive evolution relies ...

Validation of large chromosomal segment deletions by chromosome painting. (a, b) FISH assays of the chr2 barcode probes and chr2 painting probes on metaphase chromosomes prepared from LeiTing. The ...

The 23rd chromosome base pair contains what are known as our sex chromosomes. For most females, this pair contains two X chromosomes, while for most males, it contains one X chromosome and one Y ...

A graduate student's curiosity has uncovered a previously unknown link between two important hallmarks of cancer: chromosomal instability and epigenetic alterations. The resulting study, which was ...
