Cloning Flashcards
How can you make animal clones?
Using embryo transplants or adult cell cloning
How are plants cloned trough cuttings?
Cuttings are take from a parent plant
Cuttings are planted to produce identical copies
What is good about plants being cloned from cuttings?
Quick and cheap process
How can plants be cloned by tissue culture?
Plant cells put in growth medium with hormones
They grow into new plants
What is good about cloning plants by tissue culture?
Quick
Little space needed
Grown all year
What is an embryo transplant?
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
How does adult cell cloning work?
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
What are issues surrounding cloning?
Reduced gene pool
Cloned animals might not be as healthy
What does reduced gene pool mean?
Less different alleles in a population
What are positives of cloning?
It can lead to a greater understanding of the development of an embryo
Help preserve endangered species
How can plants be cloned?
From cuttings and by tissue culture
