Organisms, both prokaryotes (the archaea and the bacteria), and eukaryotes (such as protists and unicellular fungi), reproduce asexually through binary fission; most of these are also capable of sexual reproduction.Another type of fission is multiple fission that is advantageous to the plant life cycle.or example, in the rotifer Brachionus calyciflorus asexual reproduction (obligate parthenogenesis) can be inherited by a recessive allele, which leads to loss of sexual reproduction in homozygous offspring.
Angioneurotic edema can also occur as allergic reaction of other medications causing swollen tongue. Eating too hot and spicy foods can also affect the soft lining of the tongue causing inflammation. Deficiency of vitamin B12 can cause inflammation of the tongue.
