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 ...

The study of cytogenetics in Hymenoptera reveals a remarkable diversity in chromosomal number, structure and organisation across ants, bees and wasps. Research in this field has illuminated how ...

Variations in the properties of arabica coffee, such as in taste, caffeine content and disease resistance, are determined by chromosome mutations, according to a recent study. But are these findings ...

A prospective comparison of ER, PR, Ki67 and gene expression in paired sequential core biopsies of primary, untreated breast cancer. This is an ASCO Meeting Abstract from the 2015 ASCO Annual Meeting ...

Highly challenging to sequence and long overlooked, the human Y chromosome's contributions to health and disease remain largely unknown. A new paper that presents, for the first time, the complete ...

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 ...

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 ...

An appraisal. Basic tenets of cytogenetics -- The architecture of the chromosome. Viral chromosomes ; The chromosomes of protocells ; Episomes ; The chromosomes of eucells ; Euchromatin and ...
