Product Details

A new species has been discovered in the rain forest, dubbed the “sno-ball sillies” due to their snowball-shaped body segments. Students become real-world naturalists as they “breed” a pair of these creatures to identify their traits. First, students randomly pick alleles from each parent to create a unique sno-ball silly offspring. Then the class pools their data in order to determine the genotype of each parent. This fun and engaging activity makes the concepts of meiosis, genotype and phenotype, and dominant and recessive genes really come alive!

Complete for 30 students working in pairs.

Performance Expectations

MS-LS3-2: Develop and use a model to describe why asexual reproduction results in offspring with identical genetic information and sexual reproduction results in offspring with genetic variation.
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.
