Sexual reproduction implies high costs, but it is difficult to give evidence for evolutionary advantages that would explain the predominance of meiotic sex in eukaryotes. A combinational theory ...

The development of a new organism from the joining of two single cells is a carefully orchestrated endeavor. But even before sperm meets egg, an equally elaborate set of choreographed steps must occur ...

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 ...

Scientists have built a detailed timeline of the gene activity leading up to meiosis in corn, a finding with potential implications for plant breeding as well as sexually reproductive organisms more ...

Chromosome segregation is a fundamental process that is necessary for the propagation of all organisms. In meiosis there is a unique form of chromosome segregation in which sister chromatids ...
