Presentation transcript:

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

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

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

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

8n In plants can cause greater size and better growth and survival. Chapter 10 Sexual Reproduction and Genetics Polyploidy Extra sets of all chromosomes in an organism. In plants can cause greater size and better growth and survival. In humans it is lethal. 8n

Quiz Analyze how crossing over is related to variation.
