You will find numerous species which are sexual but do not need a genetic-reduction problem mainly because they will not generate males or females.
Meiotic division within the VE hypothesis arose due to the evolutionary pressures placed on the lysogenic virus due to its incapability to enter into your lytic cycle. This selective pressure resulted in the development of processes enabling the viruses to unfold horizontally through the inhabitants. The result of the range was mobile-to-mobile fusion. (This is often distinctive from the conjugation methods used by bacterial plasmids below evolutionary stress, with crucial effects.)[82] The potential of this kind of fusion is supported by the existence of fusion proteins in the envelopes from the pox viruses that make it possible for them to fuse with host membranes.
