Week 19 - Biology

Genetics & Heredity

Happy New Year and welcome back to biology! We’ll start the week connecting last month’s material to this month by introducing how gametes are created through meiosis, and how genes are passed down from generation to generation among organisms.

BY THE END OF THIS WEEK, you should be able to:

  • use all appropriate terminology found on your week 19 “Terms to Know” when discussing genetics and heredity,

  • describe the structure of a double helix and how nucleotides form to create it’s structure,

  • walk through the process of determining the statistical chances for specific genotypes and phenotypes with continuing generations using a Punnett square, and

  • describe the phases of meiosis.

Your Week Ahead

Day 1: An Introduction into Genetics

  1. We’ll start class discussing the semester exam and key points.

  2. You’ll then continue into a broader discussion connecting last month’s discussion of cell division with this week’s concept of heredity. You’ll build a double helix to better understand the right-handedness and antiparallel backbones found within it, then continue with a review of key terms for this week’s material.

  3. After class, read pages 308-315 in your textbook.

  4. Also after class, review the key terms discussed today to make sure that you feel comfortable enough to use them appropriately next class.

 

Day 2: Punnett Squares & Meiosis

  1. We’ll pick up where we left off from Day 1 then discuss how we use Punnett Squares to statistically predict possible genotypes of organisms from inherited genes using Punnett Squares, then introduce the steps of meiosis that create this possibility.

  2. After class, read pages 316-329 in your textbook and be comfortable enough with Punnett squares to complete one next class without any assistance.

IMPORTANT DATES

Did you…?

  • … complete your “Terms to Know: Week 19”? This will be especially important to do for next week.

  • … finish your readings (pages 309-326) in your textbook?

  • … study the material from this week to successfully be able to complete either a monohybrid or dihybrid cross without assistance?
