3. A genetically inherited recessive
condition in which red blood cells
are distorted resulting in severe
anemia and related symptoms that
are often fatal in childhood.
People who are homozygous for this
disease are immune to malaria but
die of the disease. Those who are
heterozygous for it have a high
degree of immunity to malaria and
have only minimal symptoms of the
4. An inherited metabolic abnormality
that is fatal in early childhood.
Eastern European Jews have an
unusually high frequency of this
harmful recessive allele in their
7. A more or less distinct group of
individuals within a species who
are reproductively isolated from
9. An alteration of genetic material
(DNA) such that a new variation in
a gene is produced.
11. The sum total of the genetically
inherited changes in the
individuals who are the members of
a population's gene pool. In other words, change in frequencies of alleles in the gene pool of a population.
12. The study of biological
inheritance patterns and changing
gene pool frequencies in
populations largely through the
determination of allele
frequencies. Researchers in this
area of study are also involved in
identifying processes resulting in
14. The name of the equation
(p²+2pq+q² = 1) used by population geneticists to determine genotype
frequencies of a population for
1. A life threatening disease found
mostly in tropical and subtropical
regions of the world. It is caused
by single-celled microorganisms
that are transmitted from person
to person by mosquitoes as they
extract blood. Symptoms of include
chills, high fever, and sometimes
fatal irregularities of the brain,
liver, kidney, and/or blood.
2. The term that encompasses all of
the genes in all of the
individuals in a breeding
5. The term for the modern theory of
evolution being caused by a number
of complex and often interacting
processes. This is essentially a
Darwin's concept of natural selection, Mendel's
genetics, along with the facts and
theories of population genetics
and molecular biology.
6. A term for a kind of evolution in
which there is a mutual,
interactive effect of biology and
culture. This term was developed
to describe the effect our culture
has on natural selection.
8. A mutation that occurs as an error
in a single codon of a DNA
9. A general term for an agent in the
environment that can cause a
mutation to occur.
10. A general term for a mutagen that
can cause a mutation in a sex cell.
13. A usually fatal, slow acting
disease caused by the Human
Immunodeficiency Virus (HIV).
Important disease-fighting white
blood cells are destroyed
resulting in a weakened immune
system. Death usually comes as a
result of cancer and other
diseases that are normally fought
off by healthy immune systems.
