Q

raw material for evolution

A

mutation

20
Q

variation in ability to attract mates

A

sexual selection

21
Q

sexual selection falls under…

A

nonrandom mating

22
Q

the highly unlikely situation in which allele frequencies do not change from one generation to the next

A

Handy-Winberg Principle

23
Q

change due to chance

A

genetic drift

24
Q

small group of individuals forms new population (religion, culture, physical, isolation)

A

founder effect

25
Q

many members of a population die leaving only a few survivors

A

bottleneck effect

26
Q

not mechanics of evolution, just how a population shrinks extremely small

A

founder effect & bottleneck effect

27
Q

migration brings in or takes away alleles

A

gene flow

28
Q

individuals or gametes can disperse

A

gene flow

29
Q

process that adapts populations to the environment (interactions that exist between species)

A

natural selection

30
Q

3 biotic/living types of natural selection

A
  • competition
  • predation
  • parasitism
31
Q

3 abiotic/nonliving types of natural selection

A
  • weather and climate
  • temperature
  • moisture
32
Q

is mutation a selection process

A

No, because it is random and slow

33
Q

if you introduced new gmo to population what would happen

A

they all die

34
Q

any shift of p^2 + 2pq + q^2 =

A

evolution

35
Q

any shift in allele frequency =

A

some force is acting on it, some type of evolution

36
Q

what does it mean when p^2 increases

A

homozygous dominant phenotypes becoming more favorable

37
Q

what does it mean when q^2 decreases

A

homozygous recessive phenotypes becoming less favorable

38
Q

2pq increases means

A

heterozygote advantage (being carriers of some diseases)

39
Q

which of the following will cause evolution to occur

  • (4/5 will remain constant, 1/5 changes)
  • (look for changes in DNA, sexual selection, gene flow, small population, natural selection
  • there’s no changes in the DNA/nucleotide sequence
  • random mating
  • no migration interlap
  • the population is large
  • environmental changes

Description of each:

  • Mutation: change in the DNA (point mutation, framshift, substitution, insertion)
  • nonrandom mating: sexual selection(birds in paradise, finches that create love mess), some phenotypes are more favorable than others, advantage to other species to pass on alleles
  • gene flow: migration interlap (in or out)
  • genetic drift: small population
  • natural selection: environmental changes

40
Q

Which of those 5 creates new alleles

A

mutation

41
Q

Which of those 5 introduces new alleles to the population through migration

A

gene flow

42
Q

Catastrophe of some type of over predation that causes shrink in population size

A

bottleneck effect

43
Q

reproductive isolation through migration or through religious or cultural means

A

founder effect

44
Q

what is specifically doing the selecting in natural selection:

  • competition, predation, parasitism = living/biotic
  • weather and climate, temperature, moisture = nonliving/abiotic
A

FREEBEE

45
Q
  • A lot of wrong answers talking about antibiotics and stuff

- development causes resistence

A

FREEBEE

46
Q

difference between natural selection and evolution

A

evolution: change in allele frequency in population over time
- micro = short amt. time
- macro = long amt. time
