Bio 212 Midterm Study Guide Questions And Answers
With Latest Updates
Which of the following processes occurs in meiosis but not in mitosis? ANS synapsis of
chromosomes
How does natural selection apply to sexual reproduction as opposed to asexual reproduction? ANS
Sexual reproduction results in many new gene combinations, some of which will lead to differential
reproduction.
Which of the following statements correctly describes the meaning of the chromosome theory of
inheritance as expressed in the early 20th century? ANS Mendelian genes are at specific loci on the
chromosome and, in turn, segregate during meiosis.
In the epistasis discussion, what color would BBee be? ANS white
Generally, only female cats have the tortoiseshell phenotype for fur color. Which of the following
statements explains this phenomenon? ANS A male inherits only one allele of the X-linked gene
controlling hair color.
What population density did invasive zebra mussels reach in a study we discussed? ANS
400,000/meter squared
Concerning sickle cell anemia (HbS), which genotype provides the best survivorship: ANS HbAS
Which factor below is not a density dependent population regulator? ANS temperature
You observe a species of bird that, upon hatching, has contact with its parents only while being fed. You
also never hear the parents sing during the feeding process. What would you propose about song learning
in this species of bird? ANS Song learning in this species is most likely innate.
Crows in a Japanese city access the meat inside nuts by: ANS dropping them into crosswalks and
waiting for the walk signal after cars have run over them
, Humpback whale songs: ANS Specific songs spread across the ocean from east australia to the Cook
Islands like hit songs in humans
What type of signal is long-lasting and works at night? ANS olfactory
A human jerking their hand away from a hot stovetop is showing: ANS innate behavior
What are the chances of a homozygous recessive offspring from mating a heterozygous parent with a
homozygous recessive parent? ANS 50%
If there are 6 heterozygous males, 6 heterozygous females, 6 homozygous recessive males, and 6
homozygous females, what is the probability of an offspring from that population being Bb? ANS
37.6%
If a cell has completed meiosis I and the first cytokinesis, and is just beginning meiosis II, which of the
following is an appropriate description of its genetic contents? ANS It has half the amount of DNA as
the cell that began meiosis.
Nucleosomes are packed into: ANS chromatin
What are the chances of an albino male and heterozygous for albinism female having an albino child?
ANS 50%
Which genotype below describes heterozygous? ANS bB
What is the term when one gene produces multiple phenotypes? ANS pleiotropy
antagonistic interactions, competition for resources, and territoriality tend to produce what dispersion?
ANS uniform
