The process of meiosis involves genetic shuffling that dilutes the desirable traits of sexually reproducing crops. Identification of a mutation in which shuffling does not occur is a step forward for ...

How is the same process responsible for genetic recombination and diversity also the cause of aneuploidy? Understanding the steps of meiosis is essential to learning how errors occur. Researchers' ...

As viewed from a human perspective, nature has done some ingenious engineering to overcome some of the obstacles it has faced. Take the evolution of sex, for instance. To make the move from asexual to ...

Mitosis and meiosis are both processes by which cells reproduce, but there are distinct differences between the two. While new cells are generated during mitosis, meiosis is a special type of cell ...

In the process of replicating themselves, cells have another choice: do they want to make an identical copy and be left with two cells? Or do they want to make four “half-copies”, in preparation for ...

Researchers have clarified how homologous chromosome pairing -- a process necessary for sperm and egg formation where paternally- and maternally-derived chromosomes match and exchange genetic ...

All cells arise from other cells through the process of cell division. Meiosis is a specialized form of cell division that produces reproductive cells, such as plant and fungal spores and sperm and ...
