New findings of researchers from the University of Modena and Reggio Emilia (Mauro Mandrioli, Valentina Monti and Gian Carlo Manicardi) show that in aphids the two X chromosomes have a different ...

Our body is composed of millions of individual cells. Each cell contains threadlike structures called chromosomes that carry genetic information from cell to cell. Chromosomes are located in the ...

Starting as a single cell, organisms undergo millions of generations of divisions to ultimately generate the bones, heart, brain and other components that make up a living being. The mainspring within ...

Mitotic chromosomes are pivotal for the inheritance of genetic material. Now, it is already known that chromosomes vary in dimensions among organisms. But what governs mitotic chromosomal size and ...

These diagrams are known as human karyotypes and show all the chromosomes aligned in pairs. The blue box shows the two sex chromosomes – these are different sizes. The X chromosome is the larger ...

Some genes just don’t play fair. Researchers have uncovered a ‘selfish’ X chromosome in the fruit fly Drosophila testacea that manages to distort inheritance in both sperm and eggs. “Researchers have ...
