Which of the following statements about dominant traits is correct?
a.
The dominant trait is the one that is expressed.
b.
They are observed three-fourths as frequently as heterozygous traits.
c.
They are observed less frequently than recessive traits.

Goswami disagrees with the Darwinian concept of canalized behavior. What are his main criticisms of the
inheritance of acquired characteristics? (Select all that apply)
Choose at least
one answer.
L
a. The Darwinian evolutionary process is very fast and can manifest in a few
generations.
b. The availability of prolonged environmental stress to produce canalization over an
entire species population is unlikely.
c. There is no evidence that learned behavior is passed down to descendants.
In the movie on rock pocket mice, what did the team discover about black colouration?
Select the ONE BEST answer.
a. Fur colouration is the result of a new adaptive behaviour where pocket mice rolled
in lava dust to camouflage themselves.
b. It is the result of the same, single mutation in all populations.
C. Different mutations cause similar dark colouration in different populations.
d. One specific mutation causes black or white fur depending on the population.
e.
Fur colouration is the result of dietary changes in different environments, not
natural selection.

- You are studying a species of beetle known as a Flumbodoodle Beetle. The beetle has long spikes on its shell to defend itself from potential predators. You are interested in studying evolution in this beetle. Which of the following studies do you not need to conduct to determine if the long spike trait can evolve by natural selection. a. A study that determines whether beetles with longer spikes survive and reproduce better than beetles with shorter spikes. b. A study that measures the spike length variation across multiple individuals in a population. c. A study where you measure the spike length on the parents and a study where you measure the spike length on the offspring. d. A study that determines whether these spikes on the beetle are also used in mate choice contexts.arrow_forwardWithin a particular population, darkly colored rats are more likely to survive than more lightly colored individuals.
