The knowledge of biodiversity in allegedly well-known places is not as complete as one would expect, and its detailed study by researchers continues to offer surprises. These are the findings from a new study of the flora ...

The evolution of a new species by hybridization from two already described species without a change in chromosome number is very rare in the animal kingdom. So far, only a few accepted empirical examples exist for this spontaneous ...

Not all species need sperm to fertilize an egg for sexual reproduction. Some species need sperm in order to induce completion of egg nucleus development, but then never use the sperm's DNA. I describe how this self-sexual ...

From avocado plants to baker's yeast, humans to zebras, sexually reproducing organisms must create germ cells that contain half the number of chromosomes found in a typical body cell. When these germ cells—such as sperm ...

Baker's yeast survive and grow after a drastic reorganization, not of their genes, but of the chromosome superstructures that house, protect and control access to their DNA code, a study just published in Nature finds.

In this age of genome sequencing, we can lose sight of the importance of how our genomes are distributed over 23 pairs of chromosomes. Rearrangements of the pairs are invisible to sequencing if the correct amount of genetic ...

Varying between organisms, the number of chromosomes, the structures of organised and packaged DNA information, are normally a constant amount, thus allowing for the successful reproduction of a species. However, it may vary ...
