    ...
    Under ideal conditions, yeast cells can reproduce through budding – mitosis followed by asymmetrical cell division (haploid). This is the most common way that yeast cells reproduce. However, under adverse conditions, yeasts can also reproduce through meiosis (diploid) and sporulation. This process begins with plasmogamy, or the fusion of the the cytoplasm. Next, the cell becomes dikaryotic (n + n) prior to fertilization. After the yeast cell is fertilized, it becomes diploid and experiences karyogamy, or the fusion of the nucleus. A diploid zygote is formed, and meiosis follows, producing a haploid spore-producing structure. This structure produces haploid spores that undergo mitosis as a means of multiplying.
    A yeast life cycle is very short, lasting only between 2-8 hours.

    Yeast can also cause what is known as candidiasis, or a yeast infection. There are about 20 species of yeast that can cause a yeast infection, the most common being candida albicans. Humans usually exist with yeast in/on our bodies without much trouble, but too much yeast causes candidiasis. Symptoms can vary depending on what part of the body is infected.

    Yeasts have also been used for recombinant DNA studies. Because of their short life cycles, ease of growth in laboratories, and relatively small genome size, as well as the fact that they share the characteristics of most eukaryotes (minus those involving multicellularity), they are commonly used as eukaryotic hosts for transgenic experimentation.
