1 Genetics 101 Give an example of a homozygous dominant genotype: –TT, AA, KK etc. True or False: the phenotype tells you what something looks like. –True

2 Genetics 101 If you cross a pure Red flower and a pure White flower and all the offspring are pink what kind of dominance are you dealing with? –Incomplete dominance

3 Genetics 101 If you cross a pure Brown cow with a pure White cow and all the offspring are Brown what kind of dominance are you working with? –Complete dominance

4 Genetics 101 Create a punnett square for a homozygous Tall plant and a Homozygous short plant. Tall is dominant over short. T T tTt tTfTt

5 Genetics 101 What would a punnett square look like for a cross between two member of the F1 generation from the previous question and what would be the chance of having a short offspring in the F2 generation? –25% T t TTTTt t tt

6 Genetics What makes a certain trait a sex linked trait? –It is a trait that is found on the sex chromsomes

7 Genetics 101 What are the three different types of mutation? –Positive –Negative –neutral

8 Genetics 101 What are the three types of mutagens? –Chemical –Biological –Physical
