Mendel and
his laws
Mendel studied
these plants and
the inheritance of
their traits
What are pea
plants?
BB is an example
of this specific
genotype
What is
homozygous
dominant?
Mendel got all tall plants
as a result of a cross
between true-breeding
tall and true-breeding
short plants because of
this law
What is the law of
dominance?
A physical
description of an
organism’s genes
What is the
phenotype?
The law that helps explain
why a parent’s alleles for a
certain gene are separated
during meiosis
What is the law of
segregation?
Black is dominant to
brown. If a brown dog
is crossed with a
homozygous black dog,
the offspring will have
this genotype
What is
heterozygous?
If you cross a
homozygous dominant
individual with a
heterozygous individual,
this percentage will be
heterozygous.
What is 50%?
The number of
different allele
combinations that are
found in gametes from
a plant with the
genotype RrYy
What is 4?
If you cross two
parents heterozygous
for 2 traits, you will
observe this phenotypic
ratio
What is 9:3:3:1?
Assume yellow peas are dominant to
green. You want to know if the pea
plants you are breeding are homozygous
or heterozygous yellow. A test cross
reveals offspring with a phenotypic
ratio of 1:1. What is the genotype of the
unknown pea plant?
What is
heterozygous?
Results when neither
allele is dominant over
the other and the
resulting phenotype is
a blend of both alleles
What is incomplete
dominance?
A cross between a white
hen and black rooster
produces speckledcolored offspring and is
an example of this type
of dominance
What is codominance?
Because of co-dominance,
a white flower crossed
with a red flower would
produce offspring with
this phenotype
What is red and
white
patches/spots?
The ABO blood
group is an example
of a gene that has
this characteristic
What is multiple
alleles?
What are the genotypes
of two parent plants if
they have 6 pink, 3
white, and 3 red
offspring.
Heterozygous
R
W
(F F )
The four blood
types
What are A, B, AB
and O?
Hemophilia is a sex-linked
recessive trait. Crossing a
mother who is a carrier for
hemophilia with a father who
has hemophilia results in this
probable percentage of sons
being born with hemophilia?
What is 50%?
Crossing a
heterozygous A
individual with an
AB individual,
results in these
phenotypes
What is A, B and AB?
A female carrier for
colorblindness would
have what genotype?
What is
heterozygous?
C
c
X X?
The reason
colorblindness is
more common in
males than females
What is the result of
colorblindness being
recessive and located
on the X
chromosome?
Thomas Morgan
studied this
organism
What are fruit
flies?
Thomas Morgan’s idea
that genes that are closer
together are more likely
to be inherited together
What is gene
linkage?
Traits that are
controlled by more than
one gene
What is polygenic?
The fraction of offspring that
will be recessive for both
traits in a dihybrid cross
between to completely
heterozygous individuals.
What is 1/16?
Assume black is dominant to
white and long fur is
dominant to short. What is
the chance of being black
with short fur if a
heterozygous black short
furred cat is crossed with a
cat heterozygous for both
traits?
What is 3/8 or
37.5%?
Make your wager
25% of offspring will
have each of these four
genotypes (RRGg,
RRGG, RrGG & RrGg),
if these two parental
genotypes are crossed
What is RrGG x
RRGg
OR
RRGG x RrGg?
