1. Warm up Quiz Describe the law of independent assortment.
Describe the law of segregation.
Analyze how these laws could lead to genetic variation.

2. Genetic Recombination
Chapter 10
Sexual Reproduction and Genetics
Genetic Recombination
The new combination of genes produced by crossing over and independent assortment
Possible combinations of genes = 2n
n is the haploid chromosome number

3. 10.3 Gene Linkage and Polyploidy
Chapter 10
Sexual Reproduction and Genetics
10.3 Gene Linkage and Polyploidy
Gene Linkage
Exception to Mendel’s law of independent assortment because linked genes usually do not segregate independently.
Genes that are close on same chromosome, Travel together during meiosis

4. If genes are linked what is a way they could separate during meiosis?

5. 8n In plants can cause greater size and better growth and survival.

In plants can cause greater size and better growth and survival.
In humans it is lethal. 8n

6. Quiz
Analyze how crossing over is related to variation.
