When does New Zealand want to be predator free? 2050
The host defines a gene drive as a way of... changing a population genetically.
removing genes from a species.
killing a population with a poisonous gene.
Which methods have already been used? traps
a grid pattern poisons
What pests / predators does Dr. Gemmell mention? rats / mice ferrets
A possum is a type of... animal
What problem associated with using poison does Dr. Gemmell NOT mention?

It takes a long time. It is dangerous.
Why does he want to target fertility?

It hasn't been tried before.
Which chromosome determines sex in humans?
What does a gene drive do? It makes genetic inheritance less random.
It eliminates a gene from a species.
It makes reproduction impossible.
How successful have scientist been on pushing a specific gene through a population?
100% about 90%
Dr. Gemmell says that it is better to reduce the female population of pests because...
females are generally more destructive.
male offspring are easier to control. limiting females in a population limits population growth.
Dr. Gemmell says the gene drive might not be successful... if wild animals don't want to mate with genetically modified animals.
if the genes cannot be controlled.
if conservationists prevent the gene drive.
Dr. Gemmell says a gene drive might be dangerous because... it could be difficult to control.
it will kill too many animals.
there has not been enough research.
Dr. Gemmell states that he prefers...
Dr. Gemmell states that introducing mammalian pests 150 years ago was...
