INTRODUCTION TO GENETICS
EXAM QUESTIONS AND CORRECT
ANSWERS
Tall pea plants are dominant over short pea plants. If
there are 200 short plants in the F2 generation from a
cross that followed Mendel's methods, about how
many plants will be tall in that generation?
600
If Mendel had crossed a true breeding dominant plant
with a true breeding recessive plant, in which of the
three generations is the recessive trait visible?
P generation and F2 generation
If a scientist wanted to follow Mendel's experiment
with a different kind of plant, which type of plant
would she examine?
A plant that has only two alleles for a trait.
The table below summarizes Mendel's results for the
F2 generation.
What number should replace the letter x in the "Seed
colour" row?
2,001
Mendel was able to study seven traits in all the pea
plants in each generation. Which of his hypotheses
allowed him to analyze each trait separably?
When gametes are formed, each gamete carries only one
allele for the gene.
