1. Warm up: 1. What is heredity? 2. Compare and contrast dominant and recessive traits. 3. On your smiley face, were any of your traits recessive? dominant from both parents?

2. QUICK CHECK!!!!!

3. Introduction to Genetics

4. We learned chromosomes contain genes and that genes are instructions to make proteins These control all our traits Gene tics is the study of heredity!

5. Alleles are the different variations of traits Most traits have 2 or more different alleles

6. If an organism has 2 of the same allele for a trait, it is called homozygous If an organism has 2 different alleles for a trait, it is called heterozygous

7. The 2 alleles an organism inherits are called its genotype (the genes the organism has) The way a genotype looks is called the phenotype

8. Scientists can predict genotypes using a Punnett square

9. In purple people eaters, one-horn is dominant (HH or Hh) and no horn is recessive (hh). Draw a Punnett square showing the cross of an un-horned purple people eater with a heterozygous purple people eater.

10. When the alleles are the same, the organism is a purebred. If the alleles are different, the organism is hybrid.

11. Warm up: 1. Complete the Punnett square below: T t T t T=tan color t=blue color Genotype(s): Phenotype(s):

12. Complete the Inheritance Gizmo www.explorelearning.com Classcode: 2E2VQZQBGJ If time remains, work on your chapter 3 review

13. Exit: How do offspring of parents who use sexual reproduction differ from offspring of a parent who uses asexual reproduction?........................................................................................................

14. Warm up: 1. Read the article. 2. Using the context of the article and the textbook, What is a mutation? 3. Why do researchers think people have blue eyes? 4. Are mutations good, bad, or neither? Explain.

23. So...what can happen because of genetics? Read the peppered moth article and answer the questions. Put your answers in the basket when you are finished.

24. Now...play the Peppered Moth simulation and see it in action! Link is on Cells and Heredity Chapter 3

25. Decorate your moths with the best "mutations" you can come up with; we will see who survives!!!!!!!!!!

26. Warm up: 1. What is the difference between a mutation and a variation? 2. How could the environment influence the diversity of a species (variation-hint peppered moth???)?
