Most of the time, when a cell in our bodies divides, each new cell carries a complete set of chromosomes. The cells involved with human reproduction, however, carry only half after division occurs. In ...

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 ...

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 ...

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 ...

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 ...

Meiosis produces sperm and eggs with exactly half the chromosome number of the individual producing the gametes. To ensure that each gamete has one copy of each chromosome pair, the diploid cell ...

Embark on an exciting journey to uncover the wonders of cell division as we explore mitosis and meiosis. In this captivating explanation, we'll delve into how cells divide and pass on genetic ...

This is known as reduction division. The four gametes produced in meiosis are genetically different. Independent assortment and the random nature of fertilisation lead to variation in living organisms ...

In a study of meiosis in budding yeast, a research team found that yeast senses temperature changes by increasing the level of DNA negative supercoils to increase crossovers and modulate chromosome ...

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

Somatic meiosis-like reduction was observed in some cells of the embryogenic callus of Arabidopsis thaliana. Two types were identified. One type was somatic chromosome reductional grouping, in which ...
