36% of your study population are homozygous recessive for
fingernail growth rate. Using the Harvey Weinberg equilibrium
equations (P+Q = 1 and P2+2PQ+Q2 = 1), calculate the frequency of
homozygous dominants and heterozygotes in your population. You may
use a calculator.
"Lumbar vertebrae" is the name we give to those vertebrae that
are only found in ___.
|
Archaeological excavations |

homozygous recessive for red hair. Which of the following is
correct (assuming a simple Mendelian gene?
|
All of the offspring will have the dark hair phenotype |
|
All of the offspring will have the heterozygous genotype |
|
One in four children will have red hair |
The iliac crest is __
|
A sharp ridge of bone at the top of the cranium in some
primates (e.g. gorillas) |
|
A ridge of bone on the superior margin of the pelvic bones |
|
A sand dune ridge where the famous “Lucy” skeleton was
discovered |
|
The preferred toothpaste of 4 out of 5 anthropologists: Iliac
Crest, it fights cavities and freshens breath |
Darwin found that individuals with some traits are more likely
to reproduce than individuals with other variants. He called this
process:
|
The inheritance of acquired traits |
|
The principle of superposition |
|
The principle of natural selection |
An “allele” is defined as __.
|
One of the variant versions of a gene |
|
A trait that has been modified from its ancestral form |
|
A trait that retains the same form that was present in the
shared ancestor of two or more taxa |
|
A disadvantageous trait that will prevent reproduction and not
be passed along to the next generation |
Sometimes a “copying error” occurs during DNA replication, which
results in offspring having a specific genetic sequence that was
not present in either of the parents. The term ___ is used to
describe those copying errors.
According to Linnaean Taxonomy, all humans are
Some traits are similar between different species, and
taxonomists describe some of those similarities as “plesiomorphic.”
By this term, taxonomists mean _
|
The trait has been changed in one or the other of the species
since the time that they last shared an ancestor in common |
|
The trait has remained the same in one or the other of the
species since the time that they last shared an ancestor in
common |
|
The trait is not dominant, and will eventually disappear from
the population |
|
The trait is interfering with reproductive success, and will
disappear from the population very soon |
The best guide to determining how closely related two or more
species are is the abundance of __
“Evolution” is often wildly misunderstood in the popular media.
Notions such as Lamarck’s “inheritance of acquired traits” and
radical change during the course of one’s life (e.g. “The X-Men” or
Pokemon) are common, but inaccurate understandings of what
evolution actually is. Over the past several weeks, we have
discussed evolution in more detail. How has your understanding of
evolution changed over the past several weeks?
(Note: there is no way to get this question “wrong” other than by
not answering it. If you tell me what you thought evolution was
about a month ago, and what you think it is about now, and how
those two viewpoints differ, you will get the full points.)
