Reproduction
es muy difícil.
This process occurs
when the cell’s
nucleus divides into
two new nuclei,
each with an exact
copy of DNA
2
Mitosis
3
This substance in
the nucleus is
shaped like a
spiral staircase
(or twisted ladder)
4
DNA
5
During DNA
replication, these
nitrogen bases
always pair up
6
Adenine with Thymine
(A)
(T)
Cytosine with Guanine
(C)
(G)
7
DNA replication
occurs during this
stage of the cell cycle
8
Interphase
9
This is the name of
each identical
strand of a
chromosome
10
Chromatid
11
These are the
factors that
control traits
12
Genes
13
The different forms
of a gene are called
14
Alleles
15
This is what scientists
call an organism that
has different alleles
for a trait than its
parents
16
Hybrid
17
With regard to the terms
“dominant and recessive”,
what does Tt mean to
a geneticist?
18
One dominant allele
and
one recessive allele
19
This term refers to
an occurrence when
alleles are neither
dominant nor
recessive
20
codominance
21
This is the likelihood
that a particular
event will occur.
22
Probability
23
This chart shows
all the possible
outcomes of a
genetic cross.
24
Punnett
Square
25
This term describes
an organism’s
genetic makeup.
26
genotype
27
An organism with
two different alleles
for a trait can be
described as
28
heterozygous
29
What is the outcome
of a cross between
a homozygous black
guinea pig (BB) and a
homozygous white
guinea pig (bb)?
30
100% chance of
offspring having
black fur (Bb)
31
This process occurs
when chromosome
pairs separate to form
new sex cells.
32
Meiosis
33
This is the number of
chromosomes each
sex cell contributes
when they combine
to produce offspring.
34
HALF the
normal number
of chromosomes
(haploid)
35
This blood type
results from a cross
between homozygous
Type A and
homozygous Type B.
36
Type AB
37
Sex-linked traits are
more common in
males than in
females because
38
A recessive allele on
the X chromosome
will always produce
the trait in a male(XY)
39
1 cell dividing into
2 cells is an example
of what type of
reproduction?
40
Asexual
Reproduction
41
Genetic disorders
are caused by…
42
mutations
43
Color blindness is an
example of a characteristic
that results totally from
__________ and is not
influenced by _________?
44
heredity;
environment
45
The basic function
of chromosomes
is…
46
Storing your
genetic info
47
What is the probability
that the offspring will
have
white
fur?

Final Jeopardy
Why is
meiosis
important?
52
Meiosis creates 4
haploid sex cells
that combine to
create a genetically
diverse diploid cell.
