3. In pea plants, the
allele for round seeds R
is dominant to the
allele for wrinkled
seeds r.
What are the predicted
results for a cross
between
Heterozygous plants?

4. What type of
inheritance is
demonstrated by the
following: Choose
dominant monogenic,
recessive monogenic,
polygenic
5. See figure 6.
Genetically describe
individuals 4 and 5 and
their parents.
6. See figure 5. How
many genes and pairs
of genes are used to
form this pigment?
What is the genotype
of the darkest red
flower?
7. See figure 4.
Describe and name this
inheritance. Polygenic
or monogenic
8. See figure 3.
Describe and name this
inheritance. Polygenic
or monogenic
9. See figure 2.
Describe the frequency
of the distribution of
polygenic traits.

11. Two black mice
have produced 24 black
and 8 white offspring in
several litters. Black
hair is dominant.
12. After several
matings, a white mouse
and a black mouse have
produced 42 black and
45 white offspring.
Describe the parents.

Black hair is dominant.
Describe the parents (genotypes). Make a punnett square.
13. Define genotype
and phenotype.
14. Describe the
outside and the inside
of a punnett square.
15. The gene for
tallness T is dominant
over the gene for
shortness t in pea
plants. A homozygous
dominant peaplant is
crossed with a
heterozygous pea plant
and 200 seeds are
produced.
16. The most common
form of human
albinism is determined
by homozygosity for
the recessive allele a. A
normally pigmented
man and woman, each
of whom has an albino
parent are married.
17. The length of fur in
guinea pigs is
controlled by a single
gene. The dominant
allele F produced short
hair and the recessive
allele f produces long
fur.
18. In pea plants, tall
plants are dominant to
short plants. If two
heterozygous tall plants
are crossed,
19. See figure 6. Is this
a dominant or recessive
trait? Describe the
genotype of individuals
1 and 5.

sibling can be taller
than another sibling.

representations of
polygenic and
monogenic traits.

If this couple has children, what is the probability that they will have an albino child?
Make a punnett square.
