The study of
heredity.
Genetics
How traits are
passed from
parent to
offspring.
Heredity
Small sections of
DNA within a
chromosome that
codes for a protein
gene
Different forms of
a gene
allele
When both alleles
are seen equally in
the offspring.
Co-dominance
What are the
expected genotypes
of a cross between
two homozygous
dominant parents?
All homozygous
dominant offspring
What phenotypic ratio would
the offspring of two
heterozygous parents for
blonde hair have? Brown hair
is the recessive trait.
Blonde : Brown
3:1
What would be the genotypic
ratio of offspring be if one
person with blue eyes, and one
person with green eyes
(heterozygous) mated. Blue eyes
are recessive to green eyes.
Gg : gg
2:2
1:1
If rolling tongue is a
dominant trait, what
would the parent
genotypes be if offspring
appeared to have the
following genotypes: RR,
Rr, rr
Rr x Rr
What type of dominance pattern
are all of the monohybrid crosses
we have done in class so far?
Complete
Dominance
In a Pedigree, what
does a square
represent?
A male
What is an example
of a way a pedigree
can be used?
Show how a trait is passed from
one generation to the other,
Determine whether allele is
dominant or recessive, Determine
whether a trait is inherited.

What is the
phenotypic ratio if
we cross parents
that are
heterozygous for
both traits?

In summer squash, white fruit color (W)
is dominant over yellow fruit color (w)
and disk-shaped fruit (D) is dominant
over sphere-shaped fruit (d).. If a
squash plant true-breeding for white,
disk-shaped fruit is crossed with a plant
true-breeding for yellow, sphere-shaped
fruit, what will the genotypic ratios be
for the F1 generation?
WwDd
1:0

In summer squash, white fruit color
(W) is dominant over yellow fruit color
(w) and disk-shaped fruit (D) is
dominant over sphere-shaped fruit (d)..
If a squash plant true-breeding for
white, disk-shaped fruit is crossed with
a plant true-breeding for yellow,
sphere-shaped fruit, what will the
phenotypic ratios be for the F2
generation?
White, disk-shaped: 9
White, sphere-shaped: 3
Yellow, disk-shaped: 3
Yellow, sphere-shaped: 1
Who developed the
model of DNA?
Watson and Crick
What is the goal of
the human genome
project?
Sequence all genes
to find locations of
alleles
When the offspring
have a blend of the
two traits.
Incomplete
dominance
The genes an
organism has for a
particular trait.
genotype
Who is the “father of genetics”
and why is he called this?
Gregor Mendel
and he figured out
patterns of traits in
offspring
