BIOL EXAM 1 STUDY GUIDE UPDATED ACTUAL
QUESTIONS AND CORRECT ANSWERS
Question:
1. Describe the key features possessed by model
organisms.
Answer:
Question:
2. Explain why it is productive to use model organisms -
why can we learn about the biology of one species
(Homo sapiens, for example, by studying the biology of
another species? (see above)
Answer:
Question:
3. Discuss the ways that genetics is important to human
health and nutrition, our environment, and agriculture.
Answer:
Question:
4. Describe how genetics can be viewed as the study of the
flow of information in biological systems.
Answer:
Question:
5. For a mutation in a DNA sequence in which one base is
replaced with another, deduce how the mRNA and
protein will be altered.
Answer:
Question:
6. Discuss the principles governing the relationship
between a gene and a trait.
Answer:
Question:
7. Distinguish between haploid and diploid (both cells and
organisms).
Answer:
, Question:
8. Explain the similarities and differences between a pair of
homologous chromosomes at any of several "zoom
levels": the DNA sequence level; the gene level; the
many genes level; the whole chromosome level
Answer:
Question:
9. Explain how (in most eukaryotes) a single meiosis
generates new genetic combinations through both
recombination between homologous chromosomes and
independent assortment of homologous chromosomes
into gametes.
Answer:
Question:
10. For genes with more than two alleles, explain the
maximum number of alleles that can be possessed by a
diploid individual, and contrast that to the number of
alleles present in a population of diploid individuals.
Answer:
Question:
11. Correctly apply the terms P, F1 and F2 to generations in a
crossing experiment.
Answer:
Question:
12. For one gene: given the genotypes and/or phenotypes of
parents and offspring, infer the dominance relationships
between alleles
Answer:
Question:
13. For one gene: given the genotypes and/or phenotype of
parents, apply the principle of segregation to predict the
possible genotypes and/or phenotypes of progeny and
their expected proportions
