EEOB 3310 FINAL EXAM QUESTIONS AND
100% CORRECT ANSWERS!!
Neotony is a form of _______ in which some adult traits are ________ in appearance
Paedomorphosis, delayed
Which of the following would be an example of hypermorphosis?
Continued growth of the brain in humans past infancy
Which of the following is true?
A. Heterochrony results after development is completed
B. Axolotls retain their gills and fins because of an iodine deficiency
C. An example of hypermorphosis is the skull morphology in humans
D. None of the above
B
Which is an example of allometric growth?
A. Cells dying off in between the digits during development to produce fingers
B. A tumor expanding in all directions pressing on internal organs
C. Long bones only growing at the epiphyseal plates or growth plates at the proximal and
distal ends resulting in elongation
D. Duplicate genes leading to specialized function
C
One part of the body growing faster or slower than other parts is an example of what?
Allometric growth
Neotony as a form of allometric growth is best represented by
Adult humans that look like juvenile stages of chimps
Developmental biology is restricted by:
Physical, biological, and phyletic constraints
, The notochord is considered vestigial in adult vertebrates, yet it is transiently necessary in
vertebrate embryos, where it specifies the neural tube. Because this structure RESTRICTS
the availability of evolutionary pathways, this is an example of
Phyletic constraint
If an organism cannot increase in size due to a lack of tissue support and tensile strength,
this is an example of
Physical constraint
What would happen if the UBX gene was mutated?
A second set of wings may grow or halters would be placed in locations where they do not
normally occur
How does a homeobox regulate Hox genes?
It is a region of the gene that codes for the protein binding region of Hox genes
Which of the following are true of Hox genes?
A. They produce transcription factors
B. They contain homeoboxes
C. They generally control how the body plans are laid out
All of the above
The occurrence of specific body parts in specific locations is determined by the
relationships between the _________ and _________ on the embryo
Genes, module locations
All insects are made up of what three modules?
Head, thorax, abdomen
If an insect has a leg where the antennae should be, this indicates a problem with the
insect's...
Modularity and Hox genes
