 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

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

name….which name the
first or last determines
relationship?
 First
 Example:
 Esox americanus
Question 8
