Developing elite fruit cultivars typically requires long breeding cycles, especially in perennial woody species. This study uncovers how sexual reproduction of a fertile triploid loquat generates a ...

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 ...

Changes in chromosome numbers may strongly affect reproductive barriers, because individuals heterozygous for distinct karyotypes are typically expected to be at least partially sterile or to show ...

We used two complementary statistical approaches to address the genetic separation between the alternative chromosomal arrangements. First, we calculated F ST between populations (across loci and for ...

A 3D graphic showing an artist's interpretation of human X and Y chromosomes. On the left are blue bundles of genetic material making an X shape and on the right blue bundles of genetic material ...
