What
chromosome is this disease found on?
What year was the disease identified and how long until it
was associated with being a genetically transferred disease?
Discuss any other genetic connections you learned about as
you investigated this disease.
How many people have this disease?
Male
= XY sex chromosomes
Female = XX sex chromosomes
Father determines the sex of baby.
How?
X or Y in the sperm
½ set of chromosomes has only one sex
chromosome
Alleles
– different forms of the same gene
Blood types A, B, AB, O
Alleles A, B, O
Controlled by Chromosome 9
Combinations

If
one parent is blood type A and the other
blood type O what are the possible children
blood types?
If
a parent is blood type A and the other
parent is blood type B what are the possible
blood types of their children?
Universal
donor?
No antigens…
Universal
receiver of
blood?
Have all the different
antigens already in
blood…
Alters
the shape of the red blood cells
A = normal allele for red blood cells
S = sickle cell allele for red blood cells
AA = normal blood type
AS = carrier of sickle cell (1/2 of cells are
normal)
SS = sickle cell disease
Identical
twins
Same egg and same sperm = same DNA
Have to be the same sex (two sisters)
.5 % of total population
Fraternal
twins
Different egg and different sperm = diff DNA
Same sex or different sex (two brothers or a
brother and sister)
Traits
that are carried on the
X chromosome
Can mothers pass traits to sons?
Can fathers pass traits to sons?
Can mothers pass traits to daughters?
Can fathers pass traits to daughters?
Hemophilia
“bleeder’s disease”
blood clots abnormally slowly or not at all
Ryan
White died in 1990 from hemophilia,
contracted AIDS from a blood transfusion,
which is necessary for hemophiliacs when
they bleed from injuries often.

Colorblindness
– can’t

Do you support abortion?
Would you abort a Down Syndrome child?
Does the state have the right to force a couple to
abort an unborn handicap child?
Would you want to genetically engineer your child?
Should it be helping people who are very sick to kill
themselves?
Amniocentesis – removal of small amount of fluid from
sac that surrounds the baby (baby cells are in the fluid –
test done between 16-18 weeks
Other tests can be done at 10-12 weeks CVS
No cures for genetic disorders WHY?
1982 – doctors tested a drug that was to change the
cells of Sickle Cell page 71
1989 – identifies gene responsible for cystic fibrosis and
changed the gene in the cell and it became normal???

Karyotype
Incomplete
Dominance
Multiple Alleles
Sex-Linked Traits
Pedigree
Karyotype
- pairing of chromatids
Nondisjunction
Occurs during meiosis when chromosomes
do not separate properly
Pedigree
shows members of a family
Amniocentesis - tests fluid around the
baby for genetic disorders
Codominant – capital letters for all
alleles
DNA
molecules= basic substances of heredity
DNA stores and passes genetic information
