Inbreeding represents a ________________ in homozygosity - Answers increase
If you are going to allow a population of mice to randomly mate for 5 generations and you want
to constrain inbreeding to 14.678481% after generation 5, how many males do you need if you
have 20 females? - Answers 5
If the effective population size is 60 individuals and there are 60 females in the population, how
many males are there? - Answers 20
If the effective population size is 64 individuals and there are 80 females in the population, how
many males are there? - Answers 20
Suppose as a breeder of Norfolk terriers, you are worried about the rate of inbreeding since the
breed is small in number. You want to make sure the rate of inbreeding in your kennel stays
below 6.25% per generation. If you have 10 females in your kennel, how few males can you get
away with. - Answers 3
How much is the frequency of the homozygous dominant genotype increased in a population
where f(A) = 0.26 and there are 40 individuals randomly mating (round to the nearest 0.0001)? -
Answers 0.0024
The homozygous dominant genotype increases in frequency in proportion to the allele
frequencies and inversely proportional to the population size.
If you observe a population to have an effective population size of 36 individuals, what is the
level of inbreeding after 9 generations (rounded to the nearest 0.001)? - Answers 0.118
How much is the frequency of the homozygous dominant genotype increased in a population
where f(A) = 0.44 and there are 20 individuals randomly mating (round to the nearest 0.0001)? -
Answers 0.0062
The homozygous dominant genotype increases in frequency in proportion to the allele
frequencies and inversely proportional to the population size.
If you observe a population to have an effective population size of 43 individuals, what is the
level of inbreeding after 4 generations (rounded to the nearest 0.001)? - Answers 0.046
How much is the frequency of the homozygous dominant genotype increased in a population
where f(A) = 0.21 and there are 60 individuals randomly mating (round to the nearest 0.0001)? -

The effective population size calculation assumes that mates are chosen __________ - Answers
randomly
The effective population size calculation also assumes that matings are __________ and remain
that way for life - Answers pairwise
When we use the (effective) population size to calculate inbreeding, we assume that all parents
make a/an ________________ contribution to the next generation - Answers equal
To reduce the level of inbreeding in a small population, we can impose a system of
_________________ mating - Answers planned
The effective population size can be altered without moving animals physically through the use
of _____________________ - Answers reproductive technology
Founders are individuals with __________ parents - Answers unknown
Quiz 2 complete beginning tabular calculations!!! - Answers Q. 1-5
As the degree of relatedness within a population increases, the level of inbreeding in that
population also increases. As relatedness and inbreeding go up, individuals become more
similar genetically and therefore genetic variability goes down. Which of the following scenarios
is correct?
1)
For the same level of increasing inbreeding in their respective populations, breeders of Poodles
should be concerned about the effects of that inbreeding on future population structure but
breeders of Icelandic Ponies need not be as concerned about the effects on future population
structure.
2)
For the same level of increasing inbreeding in their respective populations, breeders of Icelandic
Ponies and breeders of Poodles should be equally concerned about the effects of that
inbreeding on future population structure.
3)
For the same level of increasing inbreeding in their respective populations, breeders of Icelandic
