Answers
1
The ratio of frequencies of a particular genotype from one generation to the next.
Evolution
Absolute fitness
Mutation
Relative Fitness
2
Which one is FALSE about the Hardy-Weinberg principle
assumes no nat. selection, random mating, larg pop. size and no gene flow
p2 + 2pq + q2 = 0
None are false
without evolution allele + genotype frequencies in population remain equal
3
Greater weaponry increases the fitness of the individual making it advantageous to offspring
Female choice
Imprinting
Mala - Male rivalry
Sexual Dimorphism
4
Which one is TRUE? Selection pressures...
Can be biotic
Influences which individuals pass on their alleles
Can be abiotic
All are correct
5
Which of these describes a mutualistic relationship?
+ / 0
all of them
+ / +
+ / -
6
Measurements included in a time budget
frequency and duration
latency, frequency and duration
latency and frequency
duration and latency
7
An ethogram...
is the time between the stimulus occurring and the response behaviour
quantifies animal behaviour
is the number of times a behaviour occurs within the observation period
is a list of behaviours shown by a species
8
Which one is FALSE? Sexual selection...
Is random
May lead to sexual dimorphism
Can be due to male to male rivalry and female choice
None are false
9
Hazards in the field include adverse weather, difficult terrain, problems with isolation, contact with harmful organisms
True
False
10
All of these are methods of marking: banding, tagging, surgical implantation, painting and hair clipping
False
True
11
The original source of new sequences of DNA
Mutation
Evolution
Genetic drift
Disruptive selection
12
Which on is FALSE? A hazard is...
Identified in a risk assessment
Anything that can cause harm
The likelihood of harm arising from something harmful
13
Formula used to estimate population size is
M=(NR)/C
N=(MR)/C
N=(MC)/R
R=(MN)/C
14
The change over time in the proportion of individuals in a population differing in 1 or more inherited traits
Relative Fitness
Evolution
Mutation
Absolute fitness
15
Match up the phyla with an example of an organism
Platyhelminths AND flatworm
Nematoda AND flatworm
Platyhelminths AND round worm
chordate AND joint legged invertebrates
16
Which one is FALSE? Genetic drift
none are false
Is one of the drivers of evolution
includes bottleneck and founder effects
is random
17
Capture techniques are used to sample
elusive species
mobile species
sessile and slow moving organisms
none of those mentioned
18
The ratio of surviving offspring of one genotype compared to other genotypes.
Evolution
Absolute fitness
Relative Fitness
Mutation
19
Differences in characteristics between two sexes of the same species eg size and colouration
Sexual Dimorphism
Female choice
Mala - Male rivalry
Imprinting
20
Hardy-Weinberg principle: which one is TRUE?
All are true
p2+2pq+q2=1
p+q=1
if p2+2pq+q2 is NOT 1, evolution is occurring
21
What is described in this video?
Parasite - host interaction
Hardy-Weinberg equilibrium
Genetic drift
Red queen hypothesis
22
Which of these describes a symbiotic relationship?
+ / +
all of them
+ / -
+ / 0
23
What is TRUE about this tick on it's host?
All are true
It is a parasite
It has co-evolved with it's host
It benefits from the relationship whereas the host has no benefits
24
Camera traps and scat sampling are used to sample
sessile and slow moving organisms
none of those mentioned
elusive species
mobile species
25
Which one is FALSE? The mark and recapture technique assumes...
full mixing of marked indiviuals
all are wrong
an equal chance of capture of marked and unmarked individuals
limited immigration or emigration
26
Quadrats are used to sample
none of those mentioned
elusive species
mobile species
sessile and slow moving organisms
27
Which is true for genetic drift? Genetic drift is more important in ......
large populations as alleles are more likely to be lost
small populations as alleles are less likely to be lost
large populations as alleles are less likely to be lost
small populations as alleles are more likely to be lost
28
Factors responsible for increasing the rate of evolution
All of those mentioned
shorter generation times
warmer environments
sharing beneficial DNA sequences between different lineages
