what process must occur for a fungus cell to go from diploid to haploid
Meiosis is a special type of nuclear division which segregates one copy of each homologous chromosome into each new gamete. Mitosis maintains the cell's original ploidy level (for example, one diploid 2n cell producing two diploid 2n cells; one haploid n cell producing two haploid n cells; etc.).
Introduction All living things must reproduce to survive. All body or somatic cells reproduce by mitosiswhich is simple cellular reproduction. All sex cells must reduce their chromosome number as they divide. This reduction division is called meiosis and changes the chromosome number from Diploid, 2n, to Haploid, n. Each offspring resulting from the combination of haploid sex cells will contain the same chromosome number as their parents.
