===Meaning===
'''Asexual reproduction''' is when a single [[organism]] is able to produce [[offspring]] on its own.
: In '''asexual reproduction''' the only [[genetic]] [[variation]] will be due to [[Mutation|mutations]] the [[DNA]] as it is copied.
: [[Unicellular]] [[organism]]s generally undergo '''asexual reproduction'''.
: Some [[multicellular]] [[organism]]s can undergo '''asexual reproduction'''. This is observed in a number of [[Stick Insect|stick insect]] [[species]] and has been observed in turkeys when there are no [[turkeymale]]s when there in the [[population]]. ===Advantages of Asexual Reproduction===: There are advantages of '''asexual reproduction''' over [[Sexual Reproduction|sexual reproduction]]::*[[Organism]]s which '''reproduce asexually''' do not need to search for or attract a mate in order to have offspring. This saves time and [[energy]].:*'''Asexual reproduction''' is faster than [[Sexual Reproduction|sexual reproduction]] so more [[offspring]] can be made in a given time. ===Disadvantages of Asexual Reproduction===: There are disadvantages of '''asexual reproduction''' compared to [[Sexual Reproduction|sexual reproduction]]::*The [[offspring]] made in '''asexual reproduction''' are no genetically identical to their parents (except for minor [[malemutation]]s ) which leads to little [[variation]] in the [[populationspecies]]. As a result if conditions change sufficiently to harm one member of the [[species]] it will likely harm all of them in that [[habitat]].:*Since '''asexual reproduction''' is faster than [[Sexual Reproduction|sexual reproduction]] then they are more likely to be carrying [[offspring]] when environmental conditions are poor. This makes the parent and [[offspring]] more likely to die. ===References=======AQA====:[https://www.amazon.co.uk/gp/product/1782946381/ref=as_li_tl?ie=UTF8&camp=1634&creative=6738&creativeASIN=1782946381&linkCode=as2&tag=nrjc-21&linkId=5ec5fc3f6429e30c1d9ab9bca2bccf93 ''Asexual reproduction, page 207, GCSE Combined Science Trilogy; Biology, CGP, AQA '']:[https://www.amazon.co.uk/gp/product/1782945598/ref=as_li_tl?ie=UTF8&camp=1634&creative=6738&creativeASIN=1782945598&linkCode=as2&tag=nrjc-21&linkId=ad276ad49df77ab4b40ab4fd0fe09695 ''Asexual Reproduction, page 67, GCSE Combined Science; The Revision Guide, CGP, AQA '']:[https://www.amazon.co.uk/gp/product/1471851338/ref=as_li_tl?ie=UTF8&camp=1634&creative=6738&creativeASIN=1471851338&linkCode=as2&tag=nrjc-21&linkId=425855d5890466e47189e1c21b67a1ea ''Asexual reproduction, pages 177, 178-80, 183, GCSE Biology, Hodder, AQA '']:[https://www.amazon.co.uk/gp/product/0198359373/ref=as_li_tl?ie=UTF8&camp=1634&creative=6738&creativeASIN=0198359373&linkCode=as2&tag=nrjc-21&linkId=952a73bbb09d222ecc4b50d200679849 ''Asexual reproduction, pages 196, 200-201, 226-229, GCSE Biology; Third Edition, Oxford University Press, AQA '']:[https://www.amazon.co.uk/gp/product/1782945954/ref=as_li_tl?ie=UTF8&camp=1634&creative=6738&creativeASIN=1782945954&linkCode=as2&tag=nrjc-21&linkId=100574c08fbbb64318256eb79ed61a76 ''Asexual reproduction, pages 252, 255, GCSE Biology, CGP, AQA '']:[https://www.amazon.co.uk/gp/product/1471851362/ref=as_li_tl?ie=UTF8&camp=1634&creative=6738&creativeASIN=1471851362&linkCode=as2&tag=nrjc-21&linkId=7d78d70a2044ee9982dae010c94af92a ''Asexual reproduction, pages 28, GCSE Combined Science Trilogy 2, Hodder, AQA '']:[https://www.amazon.co.uk/gp/product/1782945563/ref=as_li_tl?ie=UTF8&camp=1634&creative=6738&creativeASIN=1782945563&linkCode=as2&tag=nrjc-21&linkId=9a1d023a374038e6072f33c4f3cf808b ''Asexual reproduction, pages 87, 89, GCSE Biology; The Revision Guide, CGP, AQA '']====Edexcel====:[https://www.amazon.co.uk/gp/product/1782945741/ref=as_li_tl?ie=UTF8&camp=1634&creative=6738&creativeASIN=1782945741&linkCode=as2&tag=nrjc-21&linkId=30da4f2178da182547b62a7329d13b57 ''Asexual reproduction, page 20, GCSE Combined Science; The Revision Guide, CGP, Edexcel '']:[https://www.amazon.co.uk/gp/product/1292120193/ref=as_li_tl?ie=UTF8&camp=1634&creative=6738&creativeASIN=1292120193&linkCode=as2&tag=nrjc-21&linkId=572df39392fb4200db8391d98ae6314e ''Asexual reproduction, page 27, GCSE Combined Science, Pearson Edexcel '']:[https://www.amazon.co.uk/gp/product/1782946748/ref=as_li_tl?ie=UTF8&camp=1634&creative=6738&creativeASIN=1782946748&linkCode=as2&tag=nrjc-21&linkId=a4f0348fc37d0ba1bb52d27f8679581f ''Asexual reproduction, pages 24, 33, GCSE Biology; The Revision Guide, CGP, Edexcel '']:[https://www.amazon.co.uk/gp/product/1292120207/ref=as_li_tl?ie=UTF8&camp=1634&creative=6738&creativeASIN=1292120207&linkCode=as2&tag=nrjc-21&linkId=22455ff53961978667722edaa64c0be5 ''Asexual reproduction, pages 31, 50, GCSE Biology, Pearson, Edexcel '']:[https://www.amazon.co.uk/gp/product/1782948120/ref=as_li_tl?ie=UTF8&camp=1634&creative=6738&creativeASIN=1782948120&linkCode=as2&tag=nrjc-21&linkId=dedef775c6a43dbb0a609441525adac0 ''Asexual reproduction, pages 60, 87, GCSE Biology, CGP, Edexcel ''====OCR====:[https://www.amazon.co.uk/gp/product/1782945660/ref=as_li_tl?ie=UTF8&camp=1634&creative=6738&creativeASIN=1782945660&linkCode=as2&tag=nrjc-21&linkId=83aa4500ad7759e7f401a1c5ba5df758 ''Asexual reproduction, page 69, Gateway GCSE Biology; The Revision Guide, CGP, OCR '']:[https://www.amazon.co.uk/gp/product/0198359810/ref=as_li_tl?ie=UTF8&camp=1634&creative=6738&creativeASIN=0198359810&linkCode=as2&tag=nrjc-21&linkId=d768d99f1a06f7c12fab40e5aef85a55 ''Asexual reproduction, pages 152-153, Gateway GCSE Biology, Oxford, OCR '']
