An extra copy
of Chromosome
21 causes this
What is Down
Syndrome?
Abnormally
thick mucus in
the lungs is
caused by this
What is cystic
fibrosis?
A lack of
oxygen in the
blood is caused
by this.
What is sicklecell disease?
The body lacks
the protein that
causes blood to
clot.
What is
hemophelia?
Two tools
doctors use to
detect genetic
disorders
What are
amniocentesis
and karyotypes?
Two
environmental
factors that can
effect a trait
such as height
What are diet,
medical care,
and living
conditions?
Four blood
types
What is A, B,
AB, & O?
Two types of
selective
breeding
What is
inbreeding and
hybridization?
Three methods
used to develop
organisms with
desirable traits
What are
selective
breeding,
cloning, and
genetic
engineering
A gene is said to
have multiple
alleles if it has
more than __?
What is 2?
All the DNA
in one cell.
What is a
genome?
Only people
with similar
DNA
Who are
identical
twins?
Picture of all
chromosomes
in a cell
What is a
karyotype?
The crossing of
2 genetically
similar
organisms
What is
inbreeding?
When police
compare a
suspect’s DNA
pattern with
evidence at a
crime scene
What is
DNA
fingerprinting?
Punnett Square
Showdown!
Three kids to the board!
Show the
probability of a
child being
male or female.
The sex
chromosome
a male gives
to his son.
What is a Y
chromosome?
A person can be
a carrier of a
recessive allele
but not a
dominant allele.
If you have a
dominant allele
then you have
the trait; you
don’t carry it.
Factors that can affect a
person’s height
What is genes and
environment?
The probability
that a female
hemophilia
carrier’s son will
have the trait.
What is
50%?
Reason for
many height &
skin color
phenotypes.
What is traits
are controlled
by many
genes?
Reason
bacteria is used
in genetic
engineering.
What is
bacteria
reproduces
rapidly?
