Answer
  • increases
  • maintains
  • reduces

Question 6

Question
[blank_start]Stabilizing[blank_end] selection maintains the meant trait value and [blank_start]reduces[blank_end] the variation in the trait.
Answer
  • Stabilizing
  • reduces

Genetic drift, gene flow, and mutation pressures are other ways in which evolution may occur.
Answer
  • True
  • False

Question 10

Question
Genetic drift, gene flow, and mutation pressures only enhance selection.
Answer
  • True

Question 15

Question
Immigration is always good.
Answer
  • True
  • False

Question 16

Question
Horizontal gene transfer is when genes from one species are introduced into another organism compared to vertical (parent to offspring) transmission.
Answer
  • True
  • False

Question 17

Question
Horizontal gene transfer....
Answer
  • allows for rapid acquisition of traits
  • more common among eukarya
  • more common among bacteria
  • slows down the acquisition of traits

Question 18

Question
Modern [blank_start]Synthesis[blank_end] demonstrated that [blank_start]natural[blank_end] selection operating on Mendelian variation could lead to rates of evolutionary changes that explain historical patterns of evolution.
Answer
  • Synthesis
  • natural

Question 19

Question
What equation allows evolution to be documented and qualified? [blank_start]HW[blank_end]
Answer
  • HW

Question 20

Question
Hardy-Weinberg Theroem serves as a null hypothesis for whether evolution is occurring in a population. It assumes...
Answer
  • small population
  • large population
  • random mating
  • every genotype has the same probability of mating
  • immigration
  • no immigration
  • emigration
  • no emigration
  • equal fitness
  • mutations

Question 21

Question
HW assumptions are important because any [blank_start]violation[blank_end] is a way that [blank_start]evolution[blank_end] can occur.
Answer
  • violation
  • evolution

Question 22

Question
If a difference of frequency is found between the actual and expected alleles/genotypes, then evolution has occurred/
Answer
  • True
  • False

Question 23

Question
You should practice the math questions at the end of this powerpoint.
Answer
  • True
  • False
