Document Summary
Mutation leads to variation and then selection can take place. Not all fungi create a mushroom like organism. Diploid has a single cell with one nucleus with 2 copies of every chromosomes for every cell. Haploid cell type- has single cell with one nucleus and inside is one set of chromosomes. Fungi have diploid, haploid, and heterokaryotic cell, which is a single cell with 2 nuclei with single set of chromosomes. Haploid- most fungal hypae and al spores have haploid nuclei. Diploid- diploid nuclei are found transiently during the sexual phase (if present) if they produce asexually there will be no diploid cells. Heterokaryon- unfused nuclei from different parents occupying the same unit of hypha. In some fungi this state can exist for a very long time. n+n. Asexual- default mode under stable conditions; haploid spores are produced. Fungus growing well in very good environment, will reproduce asexually. One cell reproducing into 2 cells is mitosis.
