Zoos

Question 1

What are the aims of captive breeding programmes

Answer 1

Increase population of endangered animals
Maintain genetic diversity
Reintroduce animals into the wild

Question 2

Whats the roles of zooes?

Answer 2

Conservation, research, education

Question 3

Define genetic drift

Answer 3

Change of allele freq over time resulting from organisms caryring out particular alleles failing to breed or or over breed

Question 4

Define interbredding

Answer 4

moving organisms between zoos to allow breddin increasing size of gene pool

Question 5

Define inbreeding depression

Answer 5

breeding related individuals, offspring more likely to be homozygous for harmful recessive alleles

Question 6

Describe studbooks

Answer 6

One for each species
Raw data on which all breeding plans are based on
Ensure genes from original group are retained and equally represented by encourage breeding for poorly breeded and limit those who successfully breed

Question 7

Desribe reintroducing animals into the wild

Answer 7

Only works if habitat is intact
complicated as species need to learn new skills before they can survive in the wild
could bring diseases into the habitat

Question 8

Describe scientific research

Answer 8

Increases knowledge or morphologies but they behave differently in captivity
