Reproduction (SAM COOK)

A.gigas reproduce using only sexual reproduction. This means that both a male and female need to be present in order to successfully pass on their genes. Sexual reproduction means that the cells divide through meiosis, producing two haploid cells and a genetically different progeny (Aryal, S. 2018). However, F.septica can reproduce using either sexual reproduction (when a suitable mate is present) or asexual reproduction. Asexual reproduction produces an exact replica of the parent cell resulting in a diploid cell (Aryal, S. 2018). For F.septica to reproduce asexually it has to produce spores through mitosis in the sporangium (Money, P.N. 2016). Reproducing through mitosis results in less diversity because the genetic material is an exact copy. Therefore, the offspring produced may inherit any predisposition to disease. This means that, where possible, it is evolutionarily advantageous for F.septica to reproduce sexually using a mate (Money, P.N. 2016). A.gigas cannot produce spores or reproduce through mitosis.
