Abstract

Gregor Mendel developed the principles of segregation and independent assortment in the mid-1800s based on his detailed analysis of several traits in pea plants. Those principles, now called Mendel's laws, in fact, explain the behavior of genes and alleles during meiosis and are now understood to underlie "Mendelian inheritance" of a wide range of traits and diseases across organisms. When asked to give examples of inheritance that do NOT follow Mendel's laws, in other words, examples of non-Mendelian inheritance, students sometimes list incomplete dominance, codominance, multiple alleles, sex-linked traits, and multigene traits and cite as their sources the Khan Academy, Wikipedia, and other online sites. Against this background, the goals of this Perspective are to (1) explain to students, healthcare workers, and other stakeholders why the examples above, in fact, display Mendelian inheritance, as they obey Mendel's laws of segregation and independent assortment, even though they do not produce classic Mendelian phenotypic ratios and (2) urge individuals with an intimate knowledge of genetic principles to monitor the accuracy of learning resources and work with us and those resources to correct information that is misleading.

澄清孟德尔遗传与非孟德尔遗传。
19 世纪中期,孟德尔(Gregor Mendel)根据他对豌豆植物若干性状的详细分析,提出了分离和独立配种的原理。这些原则现在被称为孟德尔定律,实际上解释了基因和等位基因在减数分裂过程中的行为,现在被理解为生物体内各种性状和疾病的 "孟德尔遗传 "的基础。当要求学生举例说明不遵循孟德尔定律的遗传,即非孟德尔遗传时,他们有时会列举不完全显性、共显性、多等位基因、性连锁性状和多基因性状,并引用可汗学院、维基百科和其他在线网站作为资料来源。在此背景下,本视角的目标是:(1)向学生、医护人员和其他利益相关者解释,为什么上述例子实际上显示了孟德尔遗传,因为它们遵守孟德尔的分离定律和独立分类法,尽管它们并不产生典型的孟德尔表型比;(2)敦促对遗传学原理有深入了解的个人监督学习资源的准确性,并与我们和这些资源合作,纠正误导性信息。

期刊介绍: GENETICS is published by the Genetics Society of America, a scholarly society that seeks to deepen our understanding of the living world by advancing our understanding of genetics. Since 1916, GENETICS has published high-quality, original research presenting novel findings bearing on genetics and genomics. The journal publishes empirical studies of organisms ranging from microbes to humans, as well as theoretical work. While it has an illustrious history, GENETICS has changed along with the communities it serves: it is not your mentor''s journal. The editors make decisions quickly – in around 30 days – without sacrificing the excellence and scholarship for which the journal has long been known. GENETICS is a peer reviewed, peer-edited journal, with an international reach and increasing visibility and impact. All editorial decisions are made through collaboration of at least two editors who are practicing scientists. GENETICS is constantly innovating: expanded types of content include Reviews, Commentary (current issues of interest to geneticists), Perspectives (historical), Primers (to introduce primary literature into the classroom), Toolbox Reviews, plus YeastBook, FlyBook, and WormBook (coming spring 2016). For particularly time-sensitive results, we publish Communications. As part of our mission to serve our communities, we''ve published thematic collections, including Genomic Selection, Multiparental Populations, Mouse Collaborative Cross, and the Genetics of Sex.
