Specifically, it derives from \u201callello\u201d and means \u201ctwo\u201d.<br \/>-Recessive, on the other hand, is a word of Latin origin that is the result of the sum of three clearly delimited components: the prefix \u201cre-\u201d, which means \u201cbackwards\u201d;  \"Cessus\", which can be translated as \"walked\" and the suffix \"-ivo\", which is used to indicate active or passive relationship. <\/p>\n<p>The notion of <strong>allele<\/strong> comes from <strong>allelomorph<\/strong>: what can appear in different forms.  In the field of biology, the value adopted by each <strong>gene<\/strong> which, in a pair, occupies the same space on chromosomes that are homologous.<\/p>\n<p><img decoding=\"async\" loading=\"lazy\" loading=\"lazy\" src=\"https:\/\/enorcerna.com\/wiki\/wp-content\/uploads\/2021\/06\/alelorecesivo.jpg\" alt=\"Recessive allele\" width=\"183\" height=\"144\" class=\"alignright size-full wp-image-38332\" align=\"right\"\/><strong>Recessive<\/strong>, for its part, is an adjective that in the <strong>biology<\/strong> applies to hereditary characteristics that are not expressed in the <strong>phenotype<\/strong> of the one who has them, although they can be manifested in the descendants of the individual in question.<\/p>\n<p>Understanding what a recessive allele is leads us to the notion of <strong>dominant allele<\/strong> and, above all, what is known as <strong>dominance<\/strong>.  The alleles that make up the same gene are related to each other: dominance is the masking that one allele (the dominant allele) achieves of the expression of the phenotype of the other allele (the recessive allele).<\/p>\n<p>The recessive allele, thus, is <strong>one whose phenotype expression is masked<\/strong>.  It should be noted that being dominant or recessive is relative: in a gene with three alleles, for example, one allele can be recessive with respect to another and dominant over the third.<\/p>\n<p>Recessive alleles are represented in lower case and dominant alleles in upper case. <\/p>\n<p>To manifest, recessive alleles must appear in <strong>loneliness<\/strong>.  Suppose that, in a flower, the color yellow is a recessive allele.  Thus, for the flower to be able to determine its yellow color, it must have only the alleles that express that hue.  In the case of dominant alleles, on the other hand, they prevail by appearing in single or double doses and thus manage to express their <strong>features<\/strong>.<\/p>\n<p>When we talk about human beings, we have to state that each gene is determined to have two alleles: one that comes from the father and the other that comes from the mother.  Starting from this, we find the fact that it is said that the allele that establishes that the child has brown eyes is dominant, however, the one with blue eyes is recessive.<\/p>\n<p>This means that if the couple is made up of a brown-eyed mother and father, their baby will have brown eyes.  In the event that one of the two has blue, it is most likely that the little one also has brown because of the dominant allele, unless he inherits the recessive alleles from other relatives.  <\/p>\n<\/p><\/div>\n\n\n<div class=\"kk-star-ratings kksr-auto kksr-align-center kksr-valign-bottom\"\n    data-payload='{&quot;align&quot;:&quot;center&quot;,&quot;id&quot;:&quot;4545&quot;,&quot;slug&quot;:&quot;default&quot;,&quot;valign&quot;:&quot;bottom&quot;,&quot;ignore&quot;:&quot;&quot;,&quot;reference&quot;:&quot;auto&quot;,&quot;class&quot;:&quot;&quot;,&quot;count&quot;:&quot;0&quot;,&quot;legendonly&quot;:&quot;&quot;,&quot;readonly&quot;:&quot;&quot;,&quot;score&quot;:&quot;0&quot;,&quot;starsonly&quot;:&quot;&quot;,&quot;best&quot;:&quot;5&quot;,&quot;gap&quot;:&quot;4&quot;,&quot;greet&quot;:&quot;Rate this post&quot;,&quot;legend&quot;:&quot;0\\\/5 - (0 votes)&quot;,&quot;size&quot;:&quot;24&quot;,&quot;title&quot;:&quot;recessive allele&quot;,&quot;width&quot;:&quot;0&quot;,&quot;_legend&quot;:&quot;{score}\\\/{best} - ({count} {votes})&quot;,&quot;font_factor&quot;:&quot;1.25&quot;}'>\n            \n<div class=\"kksr-stars\">\n    \n<div class=\"kksr-stars-inactive\">\n            <div class=\"kksr-star\" data-star=\"1\" style=\"padding-right: 4px\">\n            \n\n<div class=\"kksr-icon\" style=\"width: 24px; height: 24px;\"><\/div>\n        <\/div>\n            <div class=\"kksr-star\" data-star=\"2\" style=\"padding-right: 4px\">\n            \n\n<div class=\"kksr-icon\" style=\"width: 24px; height: 24px;\"><\/div>\n        <\/div>\n            <div class=\"kksr-star\" data-star=\"3\" style=\"padding-right: 4px\">\n            \n\n<div class=\"kksr-icon\" style=\"width: 24px; height: 24px;\"><\/div>\n        <\/div>\n            <div class=\"kksr-star\" data-star=\"4\" style=\"padding-right: 4px\">\n            \n\n<div class=\"kksr-icon\" style=\"width: 24px; height: 24px;\"><\/div>\n        <\/div>\n            <div class=\"kksr-star\" data-star=\"5\" style=\"padding-right: 4px\">\n            \n\n<div class=\"kksr-icon\" style=\"width: 24px; height: 24px;\"><\/div>\n        <\/div>\n    <\/div>\n    \n<div class=\"kksr-stars-active\" style=\"width: 0px;\">\n            <div class=\"kksr-star\" style=\"padding-right: 4px\">\n            \n\n<div class=\"kksr-icon\" style=\"width: 24px; height: 24px;\"><\/div>\n        <\/div>\n            <div class=\"kksr-star\" style=\"padding-right: 4px\">\n            \n\n<div class=\"kksr-icon\" style=\"width: 24px; height: 24px;\"><\/div>\n        <\/div>\n            <div class=\"kksr-star\" style=\"padding-right: 4px\">\n            \n\n<div class=\"kksr-icon\" style=\"width: 24px; height: 24px;\"><\/div>\n        <\/div>\n            <div class=\"kksr-star\" style=\"padding-right: 4px\">\n            \n\n<div class=\"kksr-icon\" style=\"width: 24px; height: 24px;\"><\/div>\n        <\/div>\n            <div class=\"kksr-star\" style=\"padding-right: 4px\">\n            \n\n<div class=\"kksr-icon\" style=\"width: 24px; height: 24px;\"><\/div>\n        <\/div>\n    <\/div>\n<\/div>\n                \n\n<div class=\"kksr-legend\" style=\"font-size: 19.2px;\">\n            <span class=\"kksr-muted\">Rate this post<\/span>\n    <\/div>\n    <\/div>\n","protected":false},"excerpt":{"rendered":"<p>In order to know the meaning of the term recessive allele, the&hellip;<\/p>\n","protected":false},"author":1,"featured_media":4546,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[3],"tags":[],"class_list":["post-4545","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-definition"],"_links":{"self":[{"href":"https:\/\/enorcerna.com\/wiki\/wp-json\/wp\/v2\/posts\/4545","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/enorcerna.com\/wiki\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/enorcerna.com\/wiki\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/enorcerna.com\/wiki\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/enorcerna.com\/wiki\/wp-json\/wp\/v2\/comments?post=4545"}],"version-history":[{"count":0,"href":"https:\/\/enorcerna.com\/wiki\/wp-json\/wp\/v2\/posts\/4545\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/enorcerna.com\/wiki\/wp-json\/wp\/v2\/media\/4546"}],"wp:attachment":[{"href":"https:\/\/enorcerna.com\/wiki\/wp-json\/wp\/v2\/media?parent=4545"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/enorcerna.com\/wiki\/wp-json\/wp\/v2\/categories?post=4545"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/enorcerna.com\/wiki\/wp-json\/wp\/v2\/tags?post=4545"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
