2. Lets Test our knowledge

3. CHROMOSOMAL THEORY OF INHERITANCE Genes are located on chromosomes like beads on a string Some genes are linked (meaning they are on the same chromosome and always inherited together).

4. SEX CHROMOSOMES: Pairs of chromosomes that determine the sex of the individual

6. BOY OR GIRL???

7. SEX Chromosome Punnett Squares

8.  Fruit fly experiments!  He looked at white eyed male fruit flies  He discovered sex -linked traits First person to link inheritance of a specific trait to particular chromosome

9. He took the white eyed male and crossed it with a purebred red eyed female to see whether the white- eyed trait might occur in the next generation

13. SEX LINKED TRAITS

14. Genes found ONLY on Y Chromosomes

16. Genes found ONLY on X Chromosomes

21. Q: What did Gregor Mendel say when he founded genetics? A: Woo’Pea’! Q: Why did the 2 genes get into a fight? A: One was too dominant Q: What did the genetic basketball coach say to his allele players? A: You guys need to play in the chromo-zone! Q: What did Gregor Mendel say to the gene? A: I am your father Q: What did one allele say to the other? A: Don’t worry I will trait you nice (Ba dum cha) Q: What did Gregor Mendel bring to the table? A: Peace..get it like peas but peace, it tried

22. Q: My mark on this test lol Q: 2 alleles walk into a bar, one allele forgot to bring his genes with him. The bartender looks and says no pants no service! Q: Gregor Mendel had a very independent assortment of peas and he was quite PEASed with it Q:Why do you think I look so good? A: Just good genes (jeans) HAHA Q: Nice genes! (jeans) lol Q: Why did one dominant allele get married to a recessive allele? A: Because it wanted to be a dominant couple Q: Mendel discovered the laws of heredity and they call him the father of genetics, he was very PEASED!
