Producing new ==Key Stage 3=====Meaning==='''Sexual reproduction''' is when two parents are need to produce [[offspring]]. ==Key Stage 4=====Meaning==='''Sexual reproduction''' is when two parent [[organism]]s share [[DNA]] to produce [[offspring]]. ===About Sexual Reproduction===: '''Sexual reproduction''' begins with the production of [[gamete]]s which are [[haploid]] [[OrganismCell (Biology)|organismscells]]. These [[gamete]]s are produced by [[meiosis]].: In '''sexual reproduction''' [[gamete]]s from each parent fuse together in [[fertilisation]] to produce a [[diploid]] using [[Sex Cell(Biology)|sex cellscell]] which is a new [[organism]].: '''Sexual reproduction''' results in [[offspring]] that are [[genetically]] different from two each parent.: [[Species]] which engage in '''sexual reproduction''' have large genetic [[variation]] within the [[population]]. This provides an advantage for the [[species]] survival as it produces more [[organism]]s which a chance of surviving a change in the environment.: '''Sexual reproduction''' takes longer than [[Asexual Reproduction|asexual reproduction]] because parent [[organism]]s have to find one another and then engage in [[intercourse]]. ===Advantages of Sexual Reproduction===: There are advantages of '''sexual reproduction''' over [[Asexual Reproduction|asexual reproduction]]::*'''Sexual reproduction''' results in a wide range of [[variation]] in their [[offspring]] which is useful in case environmental changes occur increasing the chances that some members of the [[species]] have suitable traits to survive this change.:*Due to the greater [[variation]] in [[offspring]] this allows [[Evolution by Natural Selection|evolution]] to take place more quickly. ===Disadvantages of Sexual Reproduction===: There are disadvantages of '''sexual reproduction''' over [[Asexual Reproduction|asexual reproduction]]::*[[Organism]]s which '''reproduce sexually''' need to search for or attract a mate in order to have offspring. This takes time and [[energy]].:*'''Sexual reproduction''' is faster than [[ParentAsexual Reproduction|parentsasexual reproduction]] so fewer [[offspring]] can be made in a given time. ===References=======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=ad276ad49df77ab4b40ab4fd0fe10280 ''Sexual 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 ''Sexual reproduction, pages 177, 179-80, 182, 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 ''Sexual reproduction, pages 196-201, 240-241, 265, GCSE Biology; Third Edition, Oxford University Press, 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 ''Sexual reproduction, pages 29, 35, 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 ''Sexual reproduction, pages 87, 89, GCSE Biology; The Revision Guide, CGP, 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 ''Sexual reproduction, pages, 251, 255, GCSE Biology, 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 ''Sexual reproduction, pages 12, 26, GCSE Combined Science; The Revision Guide, CGP, 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 ''Sexual reproduction, pages 13, 32, 33, GCSE Biology; The Revision Guide, CGP, 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 ''Sexual reproduction, pages 26, 84, 85, 88, GCSE Biology, 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 ''Sexual reproduction, pages 50-51, GCSE Biology, Pearson, Edexcel ''] ====OCR====:[https://www.amazon.co.uk/gp/product/1782945695/ref=as_li_tl?ie=UTF8&camp=1634&creative=6738&creativeASIN=1782945695&linkCode=as2&tag=nrjc-21&linkId=ceafcc80bcad6b6754ee97a0c7ceea53 ''Sexual reproduction, page 50, Gateway GCSE Combined Science; 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 ''Sexual reproduction, pages 152-153, Gateway GCSE Biology, Oxford, 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 ''Sexual reproduction, pages 68, 69, Gateway GCSE Biology; The Revision Guide, CGP, OCR '']
