Product Details

This simulation kit is a great alternative to conducting the full Sordaria genetics laboratory. Visual perithecium cards allow each student group to count crossed and non-crossed ascospores, to calculate the spore color gene map distance, and to comprehend the importance of this historical genetic method even in modern genetics. Five sets of each of the fifteen spore cards ensure unique results for each student group. This completely reusable kit includes reproducible student handouts, detailed Teacher Notes and enough materials for 15 pairs of students. A super value!

Performance Expectations

HS-LS3-1. Ask questions to clarify relationships about the role of DNA and chromosomes in coding the instructions for characteristic traits passed from parents to offspring.
HS-LS3-2. Make and defend a claim based on evidence that inheritable genetic variations may result from (1) new genetic combinations through meiosis, (2) viable errors occurring during replication, and/or (3) mutations caused by environmental factors.
HS-LS3-3. Apply concepts of statistics and probability to explain the variation and distribution of expressed traits in a population.
