We kicked off 4th quarter with a review of content covered during the first week of the Meiosis Unit. After a one-week interruption by Spring Break, students watched the Crash Course meiosis video (below), focusing on crossing over and homologous recombination. We wrapped up with a vocabulary review. Slides for today can be downloaded here.
In our last full day before Spring Break, students revisited their Punnett Square work from yesterday. Focusing on question #2 from the worksheet, students were challenged to write a paragraph summarizing the question and its answer using the following 7 vocabulary words: phenotype, genotype, dominant, recessive, allele, homozygous, and heterozygous. Students then shared their paragraph with their table partner as explained in the slides for today. Finally, students read the second half of chapter 4 in the Inside the Cell book.
