1. The technique of artificial
fertilization is crucial to Mendel's studies of hybrids.
Name four species of flowers on which artificial fertlization can be
performed, and explain whether they are equally suitable for an
experiment that tries to discover whether the characters of the
hybrids can be predicted given the characters of the parents.
2. Give an example of a "law"
from either physics or chemistry, and explain the difference between
scientific law and the definition of a scientific term.
3. Briefly describe how botanists in
the late 20th century decide whether two plants, that seem similar
but are not identical in appearance, are members of the same
species. Make sure to note the sources for your information.
4. Calculate the mean
of the following sequence of numbers, which represent the results
from a test given to a high school algebra class (the range of the
test was 0-100):
54, 76, 32, 97, 76, 45, 57, 67, 72, 21, 59, 93, 55, 70
5. Name at least three difficulties
Mendel would have encountered in the design of his experiments had
he chosen to study animal rather than plant hybrids. Would there
have been any advantages to studying animals?
6. Give an example of a species
of plant or animal, other than the pea species mentioned by Mendel,
that exhibits several sharply defined characters that appear in only
7. Give two examples of plant or animal
characteristics that seems to exhibit "blending"
inheritance (i.e. hybrids look like a blend of parental forms), and
two that do not seem to exhibit blending.
