Ankit Gupta Posted January 20, 2014 Share Posted January 20, 2014 would any one please explain me the life cycle of a plasmodium (malaria causing) ? there come a part where they form gametocyte , i mean how and why a single celled organism form gametes (they divide asexually) Link to comment Share on other sites More sharing options...
chadn737 Posted January 20, 2014 Share Posted January 20, 2014 From the perspective of Evolution there are tradeoffs between sexual and asexual reproduction. Sexual reproduction allows recombination to occur, creating new combinations of beneficial alleles while allowing harmful mutations to be unlinked and purged. Plasmodium has a life cycle where it reproduces asexually in humans, but undergoes sexual reproduction in mosquitos. Not all single celled organisms reproduce asexually. Many Eukaryotic single celled organisms have a sexual reproductive cycle, even yeast. Link to comment Share on other sites More sharing options...

Rajnish Kaushik Posted January 20, 2014 Share Posted January 20, 2014 ok so u should specify that earlier Link to comment Share on other sites More sharing options...

Sexual reproduction is not about having sexual organs like you and I or having sex as we think about it. Its a genetic/molecular process where different genomes are allowed to come together, producing new combinations. This occurs at the single-celled and multicellular levels of life.

Why it happens is complex, but ultimately it has to do with the advantage that comes with producing new recombinations of advantageous alleles and eliminating deleterious ones.

hypervalent_iodine Posted January 21, 2014 Share Posted January 21, 2014 http://lmgtfy.com/?q=life+cycle+of+a+plasmodium please visit this ! Moderator Note Rajnish, it's a bit rich for someone who seems to struggle so much with using Google to be posting these sorts of links in threads. It stops.
