Recently, some crop plants have been genetically modified to be immune to the effects of weed killers. Which of the following should be determined before planting the resistant crop in fields?
Could the gene for resistance negatively affect the genetic diversity of the crop itself?
Could the gene for resistance be passed on to subsequent generations of crops?
Could the gene for resistance increase the yields of the crop as compared to unmodified varieties?
Could the gene for resistance to weed killers pass naturally from the crop plants to weeds?

Question

Recently, some crop plants have been genetically modified to be immune to the effects of weed killers. Which of the following should be determined before planting the resistant crop in fields? 
Could the gene for resistance negatively affect the genetic diversity of the crop itself?
Could the gene for resistance be passed on to subsequent generations of crops?
Could the gene for resistance increase the yields of the crop as compared to unmodified varieties?
Could the gene for resistance to weed killers pass naturally from the crop plants to weeds?

all the above reasons are important but firstly it must be determined that whether the gene for resistance can be passed on to the next generations as it  a tedious job to create genetically modified seeds or seedling every time you sow the crop
