PAP BIOLOGY ----MRS. ADAMS
Question 1
 What are the chances
that the offspring will
show (phenotype) both
dominate traits?
 100%
Questions 2
 What condition does the
person with this
karyotype have?
 Down syndrome
Question 3
 What is the condition
this person has when the
fifth chromosome is
incomplete?
 Cri-du-chat
Question 3
 What term would be
used to identify the
specimen to the right?
How do you know?
 Virus…..protein coat
Question 4
 What is this specimen?
How do you know?
 Bacteria….definite shape,
cell wall, no organelles
Question 5
 What type of specimen is
this?
 Plant cell…chloroplast,
cell wall, multicellular
Question 6
 What type of specimen is
this ?
 Virus….
Question 7
 When reading a scientific
name….which name the
first or last determines
relationship?
 First
 Example:
 Esox americanus
Question 8
 What is occurring in the

the right?
 Replication
Question 9
 What is occurring where
the green arrow is
pointing?
 Transcription
Question 10
 What is occurring where
the green arrow is
pointing?
 Translation
Question 11
 Which chromosome pair
determines sex of
person?
 23 pair
 Does this person have a
normal karyotype?
 No…they have
Klinefelter’s syndrome
Question 12

will affect the offspring of
a person….one that
occurs during mitosis or
meiosis? Why?
 Meiosis ….a person will
only pass on mutations
that occur in gametes…
gametes are produced in
meiosis and passed on to
a person’s offspring

of crossing-over in
meiosis?

is homozygous recessive
and the other parent is
heterozygous? What would
be the genotype ratio?
 Yy and yy; 1:1
Question 15
 Survival of the fittest is a
phrase often used to
describe what? Does fit
always mean strength?
 Natural selection; no…it
means the organisms
with the best trait for
survival

 Which plant structure
transports water? What
about sugars?

of a plant shoot
promoting elongation of
cells on one side. This
response is known as ……
 Phototropism

 What is the most
effective way to ensure
that you do not get a
viral infections such as

responsible for
protecting our body from
disease.
