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 ...

During meiosis, sister chromatids produced by chromosome duplication are held together by Rec8, a meiosis-specific cohesion protein. Rec8 joins the whole length of the sister chromatids together ...

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 ...

The process of meiosis happens in the male and female reproductive organs. As a cell divides to form gametes: ...

The four gametes produced in meiosis are genetically different. Independent assortment and the random nature of fertilisation lead to variation in living organisms – no two organisms are the ...

While the causes are varied and range from infections to hormonal imbalances, deformities during meiosis—a specialized cell division process that creates sperm and eggs—is a leading cause.
