In Lesson 7, we learned about the Austrian monk Gregor Mendel and his pea plants. Mendel’s careful study of how pea plants inherit traits allowed him to predict the existence of genes (he called them “particles”) nearly 100 years before DNA was discovered! Students then practiced analyzing trait inheritance patterns using a Punnett Square worksheet.
Reminder: Students must upload the final draft of their Task to Ms. H’s Dropbox folder (the Final Draft folder in their class period folder) by midnight tomorrow (Friday, February 14). Students who upload the Task before the deadline and who receive a grade of Proficient or better will receive a Golden Ticket!
Picking up where we left off before Task Week, in Lesson 5 we reviewed key vocabulary related to the Central Dogma. Students received blank copies of the vocabulary worksheet and were provided with time in class to transcribe Central Dogma-related definitions. The remainder of the class period was spent working in small groups to discuss and debate whether specific traits are inherited through nature or nurture. The purpose of this lesson was to provide students with a link between proteins (encoded by genes within DNA) and phenotype (traits that are readily observed). Next, we will turn our attention to how traits are inherited: mitosis and meiosis.
