1. The gene for color blindness in humans is
found on the X chromosome. A boy has a color
blind father. Will the boy be color blind?
Explain.
2. True or False: Crossing over results in genetic
recombination.
3. A useful device for predicting the possible
offspring of crosses between different genotypes
is the _____.
4. In guinea pigs, the allele for rough coat (R) is
dominant to the allele for smooth coat (r), and
the allele for black fur (B) is dominant to the
allele for white fur (b). If two guinea pigs that
are heterozygous for rough, black fur are mated,
A. What are the genotypes of the parents B.What
is the phenotypic ratio of the offspring? Show
your work in a Punnett square
5. Describe Mendel’s law of segregation and law
of independent assortment.
6. Cells containing two alleles for each trait are
called _______.
7. The gamete that contains genes contributed
only by the mother is _____.
8. A couple has two children, both of whom are
boys. What is the chance that the parents' next
child will be a boy?
9. A female guinea pig homozygous dominant
for black fur color is mated with a male
homozygous for white fur color. In a litter of
eight offspring, there would probably be _____.
10. Genes located on homologous chromosomes
may have alternate forms that control different
forms of a trait. These alternate forms of a gene
are called _____.

plant and only pink-flowering plants are
produced is _____.
12. A trait controlled by four alleles is said to
have _____.
