Top-down effects imply control through predation, including fishery, while
bottom-up effects imply control through food abundance, often thought to be driven by climate or nutrient load.

It totally depends upon whether modification is being done in somatic cells or germ cells. Somatic cells modification is ethically accepted because it doesn't pass from one generation to another generation but germline modification is considered as unethical because the modification will pass on to the next generation leading to the persistence of modification in future generations. The problem with genetic modifications is that the impacts of modifications are unpredictable, rather than being fruitful they may lead to lethal mutations so if it occurs in just somatic cells, then even if it is lethal/harmful, it will be confined to only that individual but if a lethal mutation occurs in germ cells then it will pass on to the subsequent generations and it will persist in all future generations.
Answer:
The female will not inherit a sex linked disorder if her father suffers rather "have chances or the disorder if the mother is the carrier" for the disorder.
Explanation:
A female has 2 X chromosome, which she got from her parents each. The females will get the disorder or the defective gene if the mother has defective X chromosome or if the father is carrying the same disorder from his father(grandfather). In both the cases the female will be the carrier and have chances to inherit the defect to the offspring. But the female will not affect as the male will. As the female has 2 X chromosomes, and hence the dominant X will compensate for the error in recessive X.
