Genetics Lab Final Exam UPDATED
ACTUAL Exam Questions and CORRECT
Answers
What are the steps of the scientific method? - CORRECT ANSWER - Observe --> Ask a
Question --> Hypothesize --> Experiment --> Analyze Results --> Report/Replicate
Which of the following is an example of descriptive science? - CORRECT ANSWER -
Recording the hunting patterns of big cats
According to Mendel's hypothesis of dominant/recessiveness, If an individual receives two
________ "units of inheritance" for a gene, one can be _________ to the other. - CORRECT
ANSWER - Dissimilar/dominant
Suppose that shell color in turtles is due to "Gene B". The B allele (brown shell) is dominant to
the b allele (green shell). If a true-breeding brown turtle (BB) mates with a turtle with two
different alleles (Bb), what is the probability that their offspring (F1) will have green shells? -
CORRECT ANSWER - 0%
Which is an example of a mutually exclusive event? - CORRECT ANSWER - Flipping heads
or tails on the same coin.
A good scientific hypothesis should not be (tick boxes): - CORRECT ANSWER - -Too
specific
-obvious
-vague
In the US, in an average year, 20% of people will help their parents with their printer and 50%
will carefully place a spider outside. What is the probability of the population that will both help
their parents with their printer and carefully place a spider outside? (type answer as a probability
between 0 and 1) - CORRECT ANSWER - 0
, An individual of the genotype "Aa" mates with an individual of the genotype "Aa". What is the
probability that their first two offspring will both be the "Aa" genotype? (type answer as a
probability between 0 and 1) - CORRECT ANSWER - 0.25
A: You notice that the palm tree outside your house grows faster in summer when there is much
rainfall.
B: You wonder whether it's the increase in water that is causing the increase in growth.
C: You predict that palm trees will grow more in summer (wet season) than in the winter (dry
season).
Which sentence is your scientific hypothesis? - CORRECT ANSWER -B
True or false? Each gamete carries a single allele for each gene. - CORRECT ANSWER - true
A _______ control is a treatment where no response is expected to occur. - CORRECT
ANSWER - negative
A __________ hypothesis states that there is a significant difference between treatment groups. -
CORRECT ANSWER - alternative
P values can be defined as: - CORRECT ANSWER - The probability that your observed
deviations can be attributed to chance alone.
If you get an insignificant p-value > .05 , you accept your null hypothesis. - CORRECT
ANSWER - accept
You are crossing purple-flowered and white-flowered pea plants. Based on a Punnett square, the
F2 generation should have a 3:1 ratio of purple to white plants. If your actual F2 generation
consists of 750 individuals, what is your expected value for purple plants? - CORRECT
ANSWER - 562.5
