8
This combination of
chromosomes codes for a
boy.
9
What is XY?
10
With codominance you
would expect a red
flower crossed with a
white flower to give this
kind of offspring.
11
What is red and
white spotted or
striped?
12
In incomplete
dominance you would
expect a white mouse
crossed with a black
mouse to have this
coloring.
13
What is gray?
14
Create a punnet
square showing the
cross of a purely
recessive parent
with a heterozygous
parent.
155
16
Females that do not
express a trait but
can pass the trait on
to their offspring
17
What is a carrier?
18
This term
refers to two
forms of a
Gene (Ex: Eye
Color)
19
What are alleles?
20
Genotype referred
to as being “Pure”
21
What is
homozygous?
22
Heterozygous
genotypes are also
called this
23
What are hybrids?
24
Two forms that a
gene or allele may
take
25
What are dominant
or recessive?
26
Family record showing
the inheritance of a
trait over several
generations
27
What is a pedigree?
28
This process results in
4 cells with half the
original amount of
DNA.
29
What is meiosis?
30
Identify this stage of
Mitosis:
31
What is anaphase?
32
These are the
purposes for
mitosis.
33
What are growth
and repair?
34
Meiosis takes place in
this organ system.
35
What is the
reproductive
system?
36
Crossing over occurs
during this phase of
meiosis.
37
What is Metaphase
I?
38
Cross involving 2
traits
39
What is dihybrid?
40
Used to solve
genetic crosses
41
What is a Punnett
Square?
42
Percentage of
offspring that would
show dominant
phenotypes from
mating two
heterozygous parents.
43
What is 75%?
44
You would find this
percentage of
recessive phenotypes
when crossing two
heterozygous parents.
45
What is 25%?
46
Genotype ratio
resulting from
crossing two hybrid
plants
47
What is 1:2:1?
48
The probability of
getting hybrids
from a cross of a
pure dominant and
pure recessive
parents
49
100%
50
These traits are
carried on X and Y
chromosomes.
51
What are sexlinked?
52
Only these people can
be carriers for
recessive diseases on
X chromosomes.
53
What are females?
54
Disorder caused by a
mutation in the X
chromosome that
causes a person to not
be able to distinguish
green and red
colorations.
55
What is color
blindness?
56
57
Number of Possible
parent allele
Combinations that
could be passed to
offspring in a
Dihybrid Cross (Give
an example for credit)
58
What is four?
59
This term refers to
the physical
appearance of an
organism.
600
What is phenotype?
61
The Law of Dominance
states that these
traits have no effect
on phenotype when
paired with a
dominant trait allele
62
What are
recessive?
63
Complete Dominance
means that recessive
traits are masked by
these
64
What are dominant
traits?
65
Multiple alleles
appearing at the
same time for
human blood type is
an example
66
What is
Codominance?
67
Gives hybrids an
appearance in between
the phenotypes of the
two parents
68
What is incomplete
dominance?
69
70
You would expect to
find this ratio of
phenotypes when
crossing two
heterozygous parents in
a Dihybrid cross.
Create the cross for full
credit.
71
What is 9:3:3:1?
