The document discusses genetics and DNA. It notes that while humans share 99.9% similar DNA, the 0.1% difference can result in traits or genetic abnormalities. Chromosomal abnormalities occur when egg or sperm cells divide incorrectly, resulting in too many or too few chromosomes. For an autosomal disorder to develop, it requires two copies of the same recessive gene. The document includes surveys about genetics knowledge and usage in everyday life.

2. Thesis
• Genetics affects everything that goes on
within your body, including the way you
fight off illnesses.

4. Every human has 99.9%
of the SAME DNA. Only
0.1% of our DNA differs!

5. Differences in DNA
• There is a 99.9% similarity within the DNA
of human beings when compared to one
another.
• The differences in DNA can be as little as a
trait given to you. Although there is only a
0.1% difference, there is nothing in our DNA
that separates us by race.

7. 1 out of 150 babies are
born with a
chromosomal
abnormality in America.

8. Abnormalities
• When the egg or sperm call develop, it is
given one set of chromosomes from each
parent. This consists of 23 chromosomes
from each parent.
• When a child is born with a chromosomal
abnormality, it is because the egg or sperm
cell divided incorrectly and received too
much or not enough chromosomes.
Interesting Facts

10. An autosomal recessive
gene MUST BE recessive
in order for the disease to
develop.

11. Autosomal disorder
• In order for an autosomal disorder or trait to
form, there needs to two copies of the same
abnormal gene.
• If the genes are dominant, then you are only
a carrier of the disease or trait because it is
required for the gene to be recessive in order
to form. Although, if it is a recessive gene, it
is the only way possible for the disease or
trait to form. Birth Defects
