Transcript Waterman 8 Chromosomes and Sex Linked Traitsx

Lets Test our
knowledge
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).
SEX CHROMOSOMES: Pairs of chromosomes
that determine the sex of the
individual

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
He took the white eyed male and crossed it with a
purebred red eyed female to see whether the whiteeyed trait might occur in the next generation
SEX LINKED TRAITS
Genes found ONLY on Y Chromosomes
Genes found ONLY on X Chromosomes
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 
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!
