Selective Breeding and Genetic Engineering

What is Genetic Engineering?

• the manipulation of an organism’s genes
• a change in an organism's genes
• a random and abrupt disruption to DNA
• the manipulation of an organism's appearance

Humans have experimented with genetic engineering ________.

• a long time
• only recently
• only in science fiction novels

What is selective breeding?

• A process in which mates pick which partner to have offspring with
• It is a process humans use to breed or reinforce desired traits into a particular organism.
• A process to get rid of beneficial traits
• A process to add harmful traits

What is an example of selective breeding by farmers?

• Mating 2 small chickens to create more large chickens
• Mating 2 large chickens to create more large chickens
• Mating 2 large chickens to create more small chickens
• Using a machine to change the DNA of a chick

Based on the notes, how can technology help with genetic engineering?

• it can be used to add, or modify genes directly into living things.
• It can prevent disorders with a 100% success rate
• It can cause birth defects
• It has no ethical issues

Scientists genetically engineer corn to be immune to corn diseases. This is BENEFICIAL because

• This causes corn to be less likely to reproduce
• This causes corn to be less likely to survive
• This causes corn to be smaller
• This allows increased production of corn

Scientists in Zoos have selectively bred white tigers to keep them the same color. This has resulted in excessive inbreeding. White Tigers in Zoos are now more likely to be born with birth defects.
