Genetic
Disorders
Complex
Inheritance
100
A genetic disorder characterized
by uncontrolled bleeding.
What is hemophilia?
This genetic disorder is shown in
the karyotype above.
What is Turner’s
Syndrome?
A dominant autosomal disorder
that is a form of dwarfism.
What is Achondroplasia?
Genetic disorder found in
European Jews that causes
blindness, mental retardation, and
muscle weakness.
What is Tay-Sachs disease?
Duchenne Muscular Dystrophy
has this pattern of inheritance.
What is sex-linked
recessive?
A cross of a white rabbit with a
black rabbit produces offspring
with grey fur. What type of
inheritance pattern does this
show?
What is incomplete
dominance?
This type of inheritance is shown
by a woman who has a
predisposition for lung cancer
and begins smoking at 15 years
old – as a result, she ends up
getting lung cancer at age 50.
What is multifactoral
inheritance?
This inheritance happens when a
brown fur squirrel is mated with
a grey furred squirrel, and the
offspring show patches of both
grey and brown fur.
What is codominance?
The phenotype ratio of offspring
in horses when two roans (a
blend of red and white colors that
result when a red horse mates
with a white horse) are crossed.
What is
1 red : 2 roan : 1 white?
A man with two normal-sighted
parents inherits his color
blindness from this person.
Who is his mother?
The probability that a gamete will
contain the genes “Ry” if the
diploid cells contain the “Rryy”
gene combinations.
What is 50% (½)?
The probability that a woman
whose first baby was a boy will
give birth to a second baby boy.
What is 50%?
The likelihood that a child with
type O blood type has a mother
with type A blood and a father
with type AB blood.
What is 0%?
In Four O’Clocks, the gene for
red flowers (R) is incompletely
dominant to the gene for white
flowers (W). A cross between a
white flower and a red flower
would result in this percentage of
pink flowers.
What is 100%?
The probability that a man with
normal color vision and a woman
who had a colorblind father and a
normal mother will have a boy.
What is 50% (½)?
An organized picture of a
person’s chromosomes in which
chromosomes are arranged and
numbered by size, from largest to
smallest.
What is a karyotype?
Most sex-linked genes are found
on this chromosome.
What is the X chromosome?
How you can tell if a trait or
disorder in a pedigree is sexlinked.
What is if it affects males
more than females?
The failure of homologous
chromosomes to separate from
one another during meiosis.
What is nondisjunction?
Cells that contain one allele per
trait.
What are haploid cells
(gametes)?
The monomers for proteins.
What are amino acids?
The organelles in which the
electron transport chain takes
place.
What are mitochondria?
The sequence of nucleotides on
the mRNA if the sequence on the
DNA is as follows:
ATGCAT
What is UACGUA?
The phase of meiosis in which
crossing over takes place.
What is Prophase I?
An organism that makes its own
food.
What is an autotroph?
