1 12/8- 7th Grade Agenda Learning Objective: Learn about Genetics
Collect HW: Reading & Notetaking p Classwork: Chap 10 Study Guide Textbook Reading p HW: Reading & Notetaking p.191 Reminder HW: Science Fair Background due 1/13 & 1/14 (10 Points) Reminder HW: Bring a flower due 12/9 & 12/10 (5 Points) Reminder: Chapter 10 Test on 12/11 &12/12

2 Reflection Prompt: Why are there more Angiosperms than Gymnosperms?

3 Reminder Homework for 12/9 & 12/10
HW: Bring a large flower in a plastic bag w/ your name on it. that we will observe in class: Best to bring a Lilly Next best is to bring a large flower where you can see the pistil and stamen. You can go to a florist and ask them of any old flower that they are going to throw away 5 Points

4 What is Genetics? Passing of traits from parents to offspring is called Heredity Scientific Study of Heredity is called Genetics

5 Gregor Mendel 1822-1884 netics ea Austrian Priest
First to study ge_____ He grew p____ plants to study genetics netics ea

6 Mendel’s Experiment What would happen if you cross pollinate a tall plant with short plant? Why?

7 What is a allele? One part of a gene pair. Alleles represent different varieties of one trait such as height of pea plant. Two alleles form a gene pair

8 What is a Dominant Allele?
One whose trait always shows up in the organism when the allele is present Dominant allele is represented by a CAPITAL letter

9 What is a Recessive Allele?
A recessive allele is always covered up or masked whenever the dominant allele is present Recessive allele is represented by a lowercase letter

10 Phenotype Genotype TT X tt Tt X Tt TT Tt Tt tt

11 What are Genotype & Phenotype?
Phenotype: Physical appearance Genotype: Genetic makeup

12 Reminder Homework for 12/12 & 12/13
HW: Bring a large flower in a plastic bag w/ your name on it. that we will observe in class: Best to bring a Lilly Next best is to bring a large flower where you can see the pistil and stamen. You can go to a florist and ask them of any old flower that they are going to throw away 5 Points
