This site discusses misconceptions about the most commonly used human genetic traits in classrooms and labs. The site concisely summarizes why the use of these traits is spreading misinformation about Mendelian traits and offers a few suggestions for replacement. This site is most appropriate for instructor preparation, especially for high school or college instructors.
Type of Material:
Collection
Recommended Uses:
As preparation material for instructors.
As a source of information for student research projects.
Technical Requirements:
Browser.
Identify Major Learning Goals:
Unfortunately, what textbooks, lab manuals and web pages say about many human genetic traits is mostly wrong. Most of the common, visible human traits that are used in classrooms do NOT have a simple one-locus, two-allele, dominant vs. recessive method of inheritance. This website seeks to provide information refuting the common traits mistaken for Mendelian traits and offere alternatives.
Target Student Population:
High School, College General Ed, College Lower Division, College Upper Division, Graduate School
Prerequisite Knowledge or Skills:
Basic knowledge of genetics is useful. The site is very simple technologically and requires no special software or knowledge.
Content Quality
Rating:
Strengths:
The content is accurate and excellent quality
The site provides references for each topic
The site provides links to the appropriate OMIM Entry
The site covers 19 common traits used in biology classes and textbooks as ostensibly Mendelian
Concerns:
The "Who's my daddy" section contains an inappropriate assumption about paternity and is not necessary in this context.
Potential Effectiveness as a Teaching Tool
Rating:
Strengths:
Provides excellent material and context to encourage the update of commonly taught genetics misconceptions.
Uses research-based facts to support content.
This site includes a defense of teaching honest genetics and not relying on erroneous examples, however convenient they may be
Concerns:
The site has not been updated recently--perhaps not necessary, but due to its patent value to instructors, more regular upating would be appreciated
Although this site includes an alternative (cat genetics), more information on how to accomplish this would be useful
Ease of Use for Both Students and Faculty
Rating:
Strengths:
The site is clearly organized
The writing is accessible to people with only basic science background
The links all appear to work
The site includes engaging figures that increase its appeal
Concerns:
None
