Clone your animal method 1.
•
•
•
•
Ingredients: somatic cell and egg cell
Remove the nucleus from the egg
Remove the nucleus from the somatic cell
Inject the nucleus from the somatic cell
into the enucleated egg
• Stimulate growth
• Implant into surrogate mother.
Clone your animal method 2.
• Ingredients: somatic cell and egg cell
• Remove the nucleus from the egg
• Fuse the somatic cell with the enucleated
egg cell
• Stimulate growth
• Implant into surrogate mother.
• How do they do it?
Task
• Collect a somatic cell and write on it the name
of the animal of origin and its pet name
• Collect an egg cell from the same type of
animal, give it a pet name & remove the
nucleus
• Implant the nucleus from the somatic cell into
the egg cell
• Does the offspring have the same genes as
the somatic parent or the animal that donated
the egg cell?
Transgenic organisms
• Create a zygote and introduce a new useful
gene
• Implant the animal into a surrogate mother
• The grown animal should now exhibit the
trait that the gene implanted into the
nucleus carried
• Antibodies or enzymes in milk for example
Who should be allowed to
manipulate their embryos?
1. After having 3 boys they want a girl this
time.
2. The husband want to ensure he will have
a child free from haemophilia
3. Beautiful parents want to ensure their
child can be a supermodel too
4. Parents want to ensure their son can be
a pilot too, they need to be sure mum
won’t pass on the colour-blindness gene.
