Cloning Flashcards
To clone plants from cuttings, what is the process?
YOU CAN TAKE CUTTINGS FROM A GOOD PARENT PLANT EACH WITH A NEW BUD ON, KEPT IN MOIST CONDITIONS UNTIL READY TO PLANT, PLANTED AND THEN YOU HAVE GENETICALLY IDENTICAL CLONES OF THE PARENT PLANT
How can you clone plants using tissue culture?
A FEW PLANT CELLS ARE PUT IN A GROWTH MEDIUM WITH HORMONES, THEY GROW INTO NEW PLANTS - CLONES OF THE PARENT PLANT
What are the pros of using tissue culture as a method of cloning plants?
CAN MADE VERY QUICKLY, IN VERY LITTLE SPACE AND BE GROWN ALL YEAR
How can you make animal clones?
USING EMBRYO TRANSPLANTS
Sperm cells are taken from a prize bull and egg cells are taken from a prize cow. The sperm are then used to artificially fertilise an egg. What then happens to the embryo?
THE EMBRYO THAT DEVELOPS IS THEN SPLIT MANY TIMES TO FORM CLONES BEFORE ANY CELLS BECOME SPECIALISED
How can the population end up resistant to a disease as a result from cloning?
WHEN CLONING YOU GET A REDUCED GENE POOL WHICH MEANS THERE ARE FEWER ALLELES IN A POPULATION. IF A POPULATION ARE ALL CLOSELY RELATED AND A NEW DISEASE APPEARS, THEY COULD ALL BE WIPED OUT AS THERE MAY BE NO ALLELE RESISTANT TO THE DISEASE
What could the study of animal clones lead to greater understanding of?
THE DEVELOPMENT OF THE EMBRYO
AGEING
AGE-RELATED DISORDERS
Plants can be cloned by what two things?
CUTTINGS AND TISSUE CULTURE
