which crisis can be improved by selective breeding? famine when scientists change the dna of a cabbage so that it has a small amount of poison from a scorpion that kill caterpillars when they try to eat them is called genetic engineering which tenet of cell theory BEST serves as a basis for this type of biotechnology? all cells come from other cells by cell division thanks to the development of transgenic plants, much of the food we eat has been altered to be better in general. this change in agricultural production has lead to new careers in genetics farmer green suggests that farmer brown should clone his best corn plant in order to produce more ears of corn per plant. farmer brown isnt sure. why might farmer broen be hesitant? cloning eliminates the ability to sexually reproduce and provide genetic variability. gene therapy, which includes the correction of defective genes is a significant part of human genome project. which of these is an application of the technique? a new gene, which codes for the protein that can repair defective genes, is introduced. what are the advantages of true breeding? consistent and predictable characteristics in future generations. which is a possible consequence of hybridization in plants? the plants become resistant to disease. which s a possible disadvantage of true breeding? no new genes are added to the future generations cloning a horse steps collect tissue from dead horse remove nucleus from dead horse skin cell collect donor egg from surrogate mother horse x ray donor egg to destroy nucleus implant desired nucelus into donor egg impregnate surrogate mare with modified egg cloned horse born match the correct biotechnology procedure dna probes, used to identify genes in a dna sample the selective breeding of wild mustard has _____ and produces at least four other regetable crops increased biodiversity
