A new method called topology weighting provides a visual summary of evolutionary relationships across the genome. This figure summarizes the relationships among 18 individual Heliconius butterflies from five distinct populations across a one million base-pair region of their genome. Each color represents a different tree of relationships among the populations. The strong excess of reddish colors in the middle of the region is due to an adaptive introgression event, in which a beneficial wing patterning allele from one species was acquired by another through hybridization, making these two species more closely related in this part of the genome than in other parts. Topology weighting could be used to explore the genomes of other species for similar signals. See Martin and Van Belleghem, pp. 429–438.

Education

Education plays a vital role at every career stage. That’s why GSA has partnered with organizations that are dedicated to providing tools and programs for students and faculty alike. From education workshops to classroom materials, a range of resources enable members of our scientific community to share, collaborate, and learn together, strengthening our collective network and skills.

Enrich your coursework with primary literature

Primers in GENETICS make it easier for instructors to use cutting-edge research to demonstrate core competencies in the classroom.

Get a mentor for the switch to active learning

Many instructors want to use effective, evidence-based methods in their classrooms. But sometimes they need help getting started with these techniques. The Promoting Active Learning and Mentoring (PALM) network is helping to close this gap by providing grants to connect faculty and postdocs with mentors in active learning methods.

Discover the science of learning

CBE-Life Sciences Education (LSE) publishes peer-reviewed articles covering a breadth of life science education topics at the K-12, undergraduate, and graduate levels, making it a valuable resource for educators across many levels and disciplines.

Craft undergraduate curricula

Looking for a reliable way to develop your undergraduate classes? Check out the Genetics Learning Framework, a list of vetted core concepts and learning objectives compiled by the GSA Education Committee.

Explore genetics classroom resources

Are you looking for inspiration for your genetics course? GSA PREP is a collection of laboratory and in-class exercises that use evidence-based teaching methods. Each of these resources was peer-reviewed and fits into the Genetics Learning Framework.

An engaging way of teaching science communication through Wikipedia

Guest post by Cassidy Villeneuve, Wiki Education. A Wikipedia writing assignment is a great opportunity for instructors to teach science communication skills on a world stage. In this kind of assignment, genetics students create or improve Wikipedia articles related to course topics. They’re especially well equipped to translate scientific concepts this way for a general audience, […]

Building infrastructure to support mentor training

Improving research mentor training requires new approaches. Mentoring is essential for the success of researchers at all career stages, but not all mentor-mentee relationships are created equal. Students from historically underrepresented backgrounds often receive less mentoring than their peers, and many mentors are not trained in how to mentor effectively. To address some of these […]

Why fruit flies belong in primary and secondary schools

Guest authors Sanjai Patel and Andreas Prokop explain why school biology lessons are important places to advocate fundamental biomedical research, and they present strategies developed by the Manchester Fly Facility to bring Drosophila research into primary and secondary classrooms. The need for fundamental biology research has perhaps never been greater than today, yet the conditions […]
