2 How This Works Read the Question Click on the button of the right answer If you are wrong you go back to the start, if you answer correctly, you move on. **Click on the buttons only, not the page*** Enter the Game

3 Genetics

4 Genetics Continued

5 1. What are Mendel’s Laws? A Law of Segregation B C Law of Independent assortment Both Law of Segregation and Law of Independent Assortment

6 BACK TO QUESTION

7 Right!!!!!!!! Both the Law of Segregation and the Law of Independent Assortment are included in Mendel’s Law The Law of Segregation states that each allele segregates separately. One of each homologous chromosomes goes to each new cell. The Law of Independent Assortment states that in a dihybrid cross, each trait is independent of the other. BACK TO GENETICS PAGE
