The
table you sit at is your team
I will put a question up on the
board
First group who has the correct
answer will receive the point
The group with the most points
at the end will receive a
fabulous prize!
What
is the complete genetic
material contained in an
individual?
Genome
What
is a threadlike
structure of a nucleic acids
and protein found in the
nucleus of most living cells?
DNA
What
is a genotype of an
individual with two different
alleles for a given trait?
Heterozygous
What
are the possible
genotypes for straight hair
 Straight(S)
curly(s)
hair is dominant to
SS
Ss
All
chromosomes except the
sex chromosomes are called
Autosomes
Occurs
when the phenotype
of the offspring is in between
the phenotypes of the two
parnets
Incomplete
Dominance
A
trait that is carried on the
sex chromosomes is called?
Sex
– link trait
What
is a segment of DNA
that codes proteins?
Gene
What
shape is DNA in?
Twisted
Ladder
Double Helix
Where
in the cell are all the
chromosomes located?
Nucleus
What
are the four bases that
make up the rungs of the
DNA Ladder?
 Thymine
 Adenine
 Guanine
 Cytosine
Who
was the founder of
genetics?
Gregor
Mendel
How did Mendel discover
genetics?
Crossing
pea plants and
looking at different traits
from the cross
What
are some of the traits
Mendel looked at?
 Flower
color
 Seed color
 Seed shape
 Pod shape
 Pod color
 Flower position
 Stem height
What
is a breeding
experiment that tracks the
inheritance of two traits?
Dihybrid
cross

this punnett square shows
incomplete dominance, what
are the possible phenotypes?

 Red
 Pink
 White
 Explain
co-dominance
When
the heterozygous offspring
show both phenotypes
 Explain
the difference between
genotype and phenotype
 Phenotype
= visible trait determined
by the genotype
 Genotype = the genetic make up of
an organism
 When
two alleles in a gene pair are
different, then one allele can
control the expression of the trait
and the other can be hidden is
called?
Law
of Dominance
 An
individual who has the allele for
a trait or disease but does not have
the disease or outwardly express the
trait is called?
Carrier
 Reproductive
Cell
Gamete
Any
characteristic that can be
passed be inherited from parent
to offspring
Trait
What
is a pedigree?
A
diagram of the genetic
history of an individual
