Question | Answer |
What are plant cuttings? | Cuttings of buds of parent plants that are kept in moist conditions until they are ready to plant to create a genetically identical copy of the parent plant |
What are tissue cultures? | A few plant cells are put in a growth medium with plant hormones and grow in to clones of the parent plant |
What are some advantages to tissue cultures?(3) | • Can be grown all year round • Quick • Take up little space |
How do you clone animals using EMBRYO TRANSPLANTS?(5) Tyson Fury Shags Immigrants | • Take the gametes from a prize animal • Use sperm to artificially fertilise egg cell • Split embryo many times before cells become specialised to create clones • Implant embryos in to many other female animals where offspring develops •Lots of animal |
Explain how ADULT CELL CLONING is done.(4) | • Remove unfertilised egg cell and remove nucleus • Insert complete set of chromosomes in to egg cell • Electric shock egg cell to divide cell • Implant in to surrogate mother when embryo is ball of cells and clone of original body cell will develop |
What is a big issue with cloning? Explain why it is. | You can get a reduced gene pool. This means fewer different alleles in one population so poor resistance to infection due to similar genes could wipe out the population. |
How could cloning be used to benefit animals?(2) | • Could be used to protect endangered species from extinction • Can lead to greater understanding in age related diseases and embryo development |
What do some people worry about cloning?(2) | • It could cause bad health for cloned animals • People could choose babies |
