describing the terms monohybrid cross and dihybrid involves organ-
cross? isms that are het-
erozygous for two
characters that
are being studied,
and a monohybrid
cross involves or-
ganisms that are
heterozygous for
only one character
being studied.

7. 7) A sexually reproducing animal has two unlinked D) HT
genes, one for head shape (H) and one for tail length
(T). Its genotype is HhTt. Which of the following geno-
types is possible in a gamete from this organism?
8. 8) Which of the following statements correctly de- C) Traits can be
scribes how Mendel accounted for the observation dominant or reces-
that traits had disappeared in the F1 generation and sive, and the re-
then reappeared in the F2 generation? cessive traits were
"hidden" by the
dominant ones in
the F1.
9. 9) Which of the following statements correctly ex- D) All of the
plains the fact that all seven of the pea plant traits genes controlling
studied by Mendel obeyed the principle of indepen- the traits behaved
dent assortment? as if they were
on different chro-
mosomes.
10. 10) Mendel's observation of the segregation of alleles D) anaphase I of
in gamete formation has its basis in which of the meiosis
following phases of cell division?
11. 11) Mendel's law of independent assortment has its C) alignment of
basis in which of the following events of meiosis I? pairs of homol-
ogous chromo-
somes along the
middle of the cell
12. 12) Use the figure and the following description to D) 1, 2, and 3
answer the question. In a particular plant, leaf color
is controlled by gene locus D. Plants with at least
one allele D have dark green leaves, and plants with
the homozygous recessive dd genotype have light
green leaves. A true-breeding, dark-leaved plant is
crossed with a light-leaved one, and the F1 offspring
