i dont know what i can say thats not already on the sheet/s. the sheets have a lot of examples on it.
inbred plants are all genetically the same pretty much, and after a few generations, are homozygous. ie. they all have the exact same characteristics as the parent plants
hybrid plants are bred from 2 inbred plants, and they have superior performance to their parents
open pollination is just when two selected plant varieties are just allowed to inter-breed
wide crosses takes two different species to artificially create new species. they have to be fertile to be worthwhile though.
genetic engineering is asexual, and involves direct manupularion of genes on chromosomes. this is contraversial coz some people support making plants better, others argue its not natural.
