More able

Selective breeding, The founder effect and Genetic bottle neck

What is selective breeding?
Identifying individuals with desired characteristics and using them to parent the next generation
5 of 10
What is the founder effect?
When a new colony is started by a few members of an origional population. The small population size means the colony may have reduced genetic diversity than origional population

Give an example of the founder effect.
Amish people

Breeding cows to produce the most milk

What is the genetic bottle neck effect?
When there is a dramatic drop in numbers of a population. May be due to a chance event like a volcanic eruption or interference by man

Give an example of genetic bottle neck effect.
North American seals being hunted by man so very few remaining so less genetic diversity
