bio 1108 exam 1 (herrick) LATEST 2024 WITH
200+ EXPERT CERTIFIED QUESTIONS AND
ANSWERS I ALREADY GRADED A+


populations - ANSWERS-interbreeding groups of organisms of the same species
living in the same geographical area


what are two main sources that lead to genetic variation? - ANSWERS-mutation
and recombination


what can somatic mutations lead to? - ANSWERS-cancer, disease and even death
to an INDIVIDUAL


what can germ line mutations lead to? - ANSWERS-mutations that are passed
down to offspring


recombination; name two ways it can occur - ANSWERS-new alleles may be
generated through crossing over and independent assortment


allele frequency - ANSWERS-rate of occurrences of alleles in a population


gene locus - ANSWERS-the location of a certain gene/allele


allele - ANSWERS-a form of a gene; one copy of a gene

,example: A, a


how is genetic variation measured? - ANSWERS-through the allele frequency
equation


what are two factors that contribute to phenotype? - ANSWERS-genotype and
environment


species - ANSWERS-individuals that are able to exchange genetic material


gene pool - ANSWERS-all alleles present in individuals of that species


what is the allele frequency equation? - ANSWERS-AF=(# of copies of an
allele)/(total # of alleles in population)


evolution - ANSWERS-change in allele frequency or genotype frequency over time


how is evolution measured? - ANSWERS-examinable physical traits, gel
electrophoresis, DNA sequences;


most importantly: the hardy-weinberg equilibrium


what does the hardy-weinberg equilibrium model describe? - ANSWERS-the
situation in which evolution does NOT occur

, a population in the HW equilibrium meets what requirements? - ANSWERS-1.
closed population (no migration or gene flow)
2. no mutations
3. large population (no genetic drift)
4. random mating (no sexual selection)
5. no natural selection


what is the HW equation? - ANSWERS-p^2 + 2pq + q^2


natural selection occurs when... - ANSWERS-...individuals with certain traits
reproduce more offspring than do individuals without those traits


stabilizing selection - ANSWERS-against the extremes


directional selection - ANSWERS-against one extreme


disruptive selection - ANSWERS-against the mean
STRONG and QUICK


artificial selection - ANSWERS-selection by breeder rather than competition


positive selection - ANSWERS-selection that increases the frequency of a
FAVORABLE allele


negative selection - ANSWERS-selection that decreases the frequency of a
deleterious allele
