This is the reason why not<br \/>\nall copulations lead to fertilizations and pregnancy.<\/h4>\n<h4>\nv) The process of fusion of a sperm with an ovum is called fertilizations.<\/h4>\n<h4>\nvi) During fertilizations, a sperm comes in contact with the zona pellucida<br \/>\nlayer of the ovum and induces changes in the membrane that block<br \/>\nthe entry of additional sperms. Thus, it ensures that only one sperm<br \/>\ncan fertilise an ovum.<\/h4>\n<h4>\nvii) The secretions of the acrosome help the sperm enter into the<br \/>\ncytoplasm of the ovum through the zona pellucida and the plasma<br \/>\nmembrane.<\/h4>\n<h4>\nviii) This induces the completion of the meiotic division of the secondary<br \/>\noocyte.<\/h4>\n<h4>\nix) The second meiotic division is also unequal and results in the<br \/>\nformation of a second polar body and a haploid ovum (ootid).<\/h4>\n<h4>\nx) Soon the haploid nucleus of the sperms and that of the ovum fuse<br \/>\ntogether to form a diploid zygote.<\/h4>\n","protected":false},"excerpt":{"rendered":"<p>Question : Trace the events from copulation to zygote formation in a human female. &nbsp; The correct answer is \u2013 i) During copulation (coitus) semen is released by the penis into the vagina (insemination). ii) The motile sperms swim rapidly, pass through the cervix, enter into the uterus and finally reach the ampullary region of [&hellip;]<\/p>\n","protected":false},"author":21842,"featured_media":131459,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[7],"tags":[],"class_list":{"0":"post-131763","1":"post","2":"type-post","3":"status-publish","4":"format-standard","5":"has-post-thumbnail","7":"category-education"},"aioseo_notices":[],"_links":{"self":[{"href":"https:\/\/www.mapsofindia.com\/my-india\/wp-json\/wp\/v2\/posts\/131763","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.mapsofindia.com\/my-india\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.mapsofindia.com\/my-india\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.mapsofindia.com\/my-india\/wp-json\/wp\/v2\/users\/21842"}],"replies":[{"embeddable":true,"href":"https:\/\/www.mapsofindia.com\/my-india\/wp-json\/wp\/v2\/comments?post=131763"}],"version-history":[{"count":1,"href":"https:\/\/www.mapsofindia.com\/my-india\/wp-json\/wp\/v2\/posts\/131763\/revisions"}],"predecessor-version":[{"id":131766,"href":"https:\/\/www.mapsofindia.com\/my-india\/wp-json\/wp\/v2\/posts\/131763\/revisions\/131766"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.mapsofindia.com\/my-india\/wp-json\/wp\/v2\/media\/131459"}],"wp:attachment":[{"href":"https:\/\/www.mapsofindia.com\/my-india\/wp-json\/wp\/v2\/media?parent=131763"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.mapsofindia.com\/my-india\/wp-json\/wp\/v2\/categories?post=131763"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.mapsofindia.com\/my-india\/wp-json\/wp\/v2\/tags?post=131763"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
