RESIDUAL QUESTIONS?
STATION MITOSIS
1. Obtain the pieces of the cell cycle puzzle from your teacher. Place the pieces in the correct order of the events of the cycle. If assembled
correctly, you will have two diagrams of the cell cycle within animals and in plants. Is this sexual or asexual reproduction? Explain.
2. List the following events in the correct sequence while describing the processes occurring within: interphase, mitosis, anaphase, metaphase,
prophase, telophase, cytokinesis.
3.The drawings A-E show stages of mitosis in an animal cell. Identify each stage below. Be careful to analyze every component present.
4. Explain the process in which chromatin becomes a chromosome.
5. Discuss how the following terms are related to one another: DNA, centromere, chromosome, and chromatid.

STATION MENDELIAN GENETICS
1. Which of the following statements is true about Mendel?
a) His discoveries concerning genetic inheritance were generally accepted by the scientific community when he published them during the mid 19th
century.
b) He believed that genetic traits of parents will usually blend in their children.
c) His ideas about genetics apply equally to plants and animals.
2. Mendel believed that the characteristics of pea plants are determined by the:
a) inheritance of units or factors from both parents
b) inheritance of units or factors from one parent
c) relative health of the parent plants at the time of pollination
3. An allele is:
a) another word for a gene
b) a homozygous genotype
c) a heterozygous genotype
d) one of several possible forms of a gene
4. Phenotype refers to the ______________________ of an individual.
a) genetic makeup
b) actual physical appearance
c) recessive alleles
5. When the genotype consists of a dominant and a recessive allele, the phenotype will be like _________________ allele.
a) the dominant
b) the recessive
c) neither
6. Assuming that both parent plants in the diagram below are homozygous, why would all of the f1 generation have yellow phenotypes?
a) because the f1 genotypes are homozygous
b) because yellow is dominant over green
c) because both parents passed on yellow alleles
7. The idea that different pairs of alleles are passed to offspring independently is Mendel's principle of:
a) unit inheritance
b) segregation
c) independent assortment
8. In the diagram below, what accounts for the green pea seed in the f2 generation?
a) On average, 1 out of 4 offspring of heterozygous parents will be homozygous recessive.
b) The yellow allele is dominant over the green one.
c) The f1 generation parents are homozygous yellow.
9. The idea that for any particular trait, the pair of alleles of each parent separate and only one allele from each parent
passes to an offspring is Mendel's principle of:
a) independent assortment
b) hybridization
c) segregation

STATION MONOHYBRID and DIHYBRID CROSSES
Part A: Vocabulary
Match the definitions on the left with the terms on the right.
____ 1. genotypes made of the same alleles
____ 2. different forms of genes for a single trait
____ 3. gene that is always expressed
____ 4. gene that is expressed only in the homozygous state
____ 5. genotypes made of two different alleles
A. alleles
B. dominant
C. heterozygous
Part B: MONOHYBRID CROSSES
1.
Gene: Height
Alleles:
Tall (T)
Short (t)
D. homozygous
E. recessive
Mom:
Homozygous recessive
Dad: Heterozygous
a. Please complete a Punnett Square to predict the offspring genotype and phenotype.
b. Which is the dominant allele?
What does being dominant tell us about this allele?
2.
Gene: Hair Color
Alleles:
Blonde hair (B) Brunette hair (b)
Mom:
Heterozygous
Dad: Heterozygous
a. Please complete a Punnett Square to predict the genotype and phenotype of the offpring.
b. Name the gene that would have Blonde and Brunette hair as two of its alleles.
c. What fraction of their children would be homozygous dominant?
Part C: DIHYBRID CROSSES
1. In horses, the coat color black is dominant (B) over chestnut (b). The trotting gait is dominant (T) over the pacing gait (t). If a homozygous
black pacer is mated to a homozygous chestnut, heterozygous trotter, what will be the ratios for genotype and phenotype of the F1
generation?
STATION SPECIAL CROSSES
PART A: Incomplete and Codominant Traits
SpongeBob and his pal Patrick love to go jellyfishing at Jellyfish Fields! The fields are home to a special type of green jellyfish known as Goobers
and only really great jellyfishermen are lucky enough to catch some on every trip. Many of the jellyfish are yellow (YY) or blue (BB), but some
end up green as a result of incomplete dominance. Use this information to help you complete each section below.
1. What would happen if SpongeBob and Patrick crossed two “goobers” or green jellyfish? Complete the Punnett square to help you determine the
probability for each color of jellyfish.
(a) Give the possible genotypes and phenotypes for the offspring.
(b) What percentage of the offspring would be yellow? _____%
(c) What percentage would be blue? _____ %
(d) What percentage would be “goobers” (green)? _____ %
2. What would happen if they crossed a yellow jellyfish with a goober? Complete the Punnett square to help you determine the probability for each color
of jellyfish.
(a) Give the possible genotypes and phenotypes for the offspring.
(b) What percentage of the offspring would be yellow? _____%
(c) What percentage would be blue? _____ %
(d) What percentage would be “goobers” (green)? _____ %
3. What would happen if they crossed a blue jellyfish with a yellow jellyfish? Complete the Punnett square to help you answer the questions.
If 100 jellyfish were produced from this cross, how many would you expect for each?
Yellow - _____
Blue - _____
Goobers - ______
PART B: Sex-Linked Traits
1. In humans colorblindness (b) is an example of a sex-linked recessive trait. In this problem, a male with colorblindness marries a female who is not colorblind but
carries the (b) allele. Using a Punnett square, determine the genotypic and phenotypic probabilities for their potential offspring.
