evolution

Question 1

Hardy-Weinberg Equilibrium
5 conditions

Answer 1

if 5 conditions met the population will stay exactly the same from generation to
generation
p^2 + 2pq + q^2 = 1
1.No mutations
2. No gene flow
3. No natural selection
4. Random mating
5. Large population

Question 2

fitness

Answer 2

the ability of an organism (based on its genotype) to survive, find a mate and produce offspring to pass on genes to the next generation

Question 3

genetic flow

Answer 3

transfer of alleles from one population to another resulting from movement of fertile
individuals or their gametes

Question 4

genetic drift

Answer 4

a process in which chance events cause unpredictable fluctuations of allele frequencies from one generation to the next

Question 5

molecular clock hypothesis

Answer 5

• based on the theory that specific DNA sequences (or the proteins they encode) spontaneously mutate at constant rates
• to estimate how long ago two related organisms diverged from a common ancestor
  (i.e. when speciation occurred)
