, UCONN BIOLOGY 1108 EXAM 1 QUESTIONS AND CORRECT
ANSWERS 2024/2025 GRADED A+
1. A scientific theory:: - Is built using inductive logic
- Is 'unprovable but falsifiable'
- Describes a lot with just a little (a model of few parts) - Makes predictions aboutfuture observations
- Scientific Method (Lab this week!)
2. Genetic variation:: differences in DNA sequences
3. What can cause genetic variation?: A mutation...
- Somatic - Germ-lineand they
can be:
- Deleterious
- Neutral
- Advantageous
then recombination gives new combinations not present in parent population
4. Allele Frequencies: Allele Frequency = # of copies of an allele/ total # of allelesin population
5. Example : A population of 100 pea plants has the following genotype fre-quencies:
50% aa, 25% Aa, 25% AA
What is the frequency of a?: • 100 a copies for the aa group
• 25 a copies for the Aa group
• 0 a copies in the AA group
• Total 125 copies of a out of 200 total alleles
• Frequency of a in this pop'n is 125/200 or 62.5%
6. The square roots of 0.5 and 0.25 do not add to 1!: Because I made them up...if they do not add to 1, then you have:
not accounted for all of the allelesor
you have not measured the freq. correctlyor
both of these
7. Gel Electrophoresis:
8. Conditions/assumptions of HW:: - No differential survival or reproductive suc-cess of individuals.
- No migration.
