1- population health

Question 1

the fundamental theorem of natural selection

Answer 1

rate of adaptation/improvement is proportional to strength of selection + amount of variation

Question 2

primary genetic risk to a breed is:

Answer 2

loss of genetic diversity

Question 3

what happens if you stop breeding carriers?

Answer 3

-creates bottleneck effect and decreases genetic diversity
-this may cause increase drift of other disorders

Question 4

rules of breeders/genetic testing

Answer 4

1. avoid selection for extreme phenotypes
2. use genetic testing to select healthy breeding animals
3. be willing to modify breeding practices

Question 5

3 ways to reduce disease allele prevalence

Answer 5

1. genetic testing of parents
2. phenotypic testing of parents
3. pedigree analysis

Question 6

what to do when you have simple autosomal recessive disorder with genetic test

Answer 6

breed with quality carriers to normal testing individuals

Question 7

why are linkage markers used for autosomal recessive disorders

Answer 7

to make sure its not a recombination event

Question 8

avoid _____ but don’t necessarily avoid some __________

Answer 8

line breeding (breeding relatives with a lower coefficient of relatedness)

Question 9
