1
Q

How can you make animal clones?

A

Using embryo transplants or adult cell cloning

2
Q

How are plants cloned trough cuttings?

A

Cuttings are take from a parent plant

Cuttings are planted to produce identical copies

3
Q

What is good about plants being cloned from cuttings?

A

Quick and cheap process

4
Q

How can plants be cloned by tissue culture?

A

Plant cells put in growth medium with hormones

They grow into new plants

5
Q

What is good about cloning plants by tissue culture?

A

Quick
Little space needed
Grown all year

6
Q

What is an embryo transplant?

A

Sperm cell and egg cell taken
Sperm used to artificially fertilise egg cell
The embryo that develops splits many times
Embryos implanted into others
They will be genetically identical

7
Q

How does adult cell cloning work?

A

Take nucleus out of unfertilised egg cell
Take a full set of chromosomes from an adult body cell
Insert into egg cell
Electric shock
Embryo implanted

8
Q

What are issues surrounding cloning?

A

Reduced gene pool

Cloned animals might not be as healthy

9
Q

What does reduced gene pool mean?

A

Less different alleles in a population

10
Q

What are positives of cloning?

A

It can lead to a greater understanding of the development of an embryo
Help preserve endangered species

11
Q

How can plants be cloned?

A

From cuttings and by tissue culture
