of the parental genomes. In eukaryotes, sex involves meiosis-mixis-cycles and is tied to reproduction. The prevalence of sexual reproduction in eukaryotes is striking because of the obvious high costs of sex [2]: first, recombination during meiosis breaks up beneficial gene combinations; associated...
Meiosis is a special form of cell division that maintains the correct number of chromosomes in gamete cells, proceeding continuously through several phases. Meiosis I is the phase in which two haploid cells are produced from a single diploid cell. What happens during the pachynema stage of ...
