Biology Students Visit Pioneer
The biology students visited Pioneer Seed Company. The focus of the trip was to learn about the tools of biotechnology and see a examples of selective breeding. The students saw the molecular marker lab, learned about SNPS, watched machines extract DNA, and looked at graphs of genetic data. The students used tools to access the female parts of soybean plants and manually cross them with specific male plants. They practiced punnett squares to analyze the trait frequency in a specific breeding population. The students also looked at teosinte: the common ancestor to all modern corn. They gained an appreciation for power of selective pressure!
