Question

Plzz help!!!

Some scientists are modifying the genetic code of certain fish by inserting genes that cause the fish to produce more growth hormone, which causes the fish to grow more quickly. Salmon is one type of fish on which scientists are working. Which answer choice shows the most significant negative impact to society that could result from producing genetically modified salmon?

Salmon cells could become less responsive to the hormone over time, slowing the growth rate of the fish.

Salmon could be reintroduced into the ecosystem where they could breed with, and alter, populations of wild salmon.

The genetically modified salmon will be very expensive to raise, so the fish will be too expensive for people to buy.

The modified, farmed fish would be more difficult for predators to hunt than wild salmon if reintroduced into the ecosystem.

Answer 1

breeding with and altering the population of wild salmon

the extra growth hormone could change the wild salmons reproductive fitness, could slow them down or make them less fertile or more fragile so they aren't able to spawn etc and reduce the wild population of salmon which would have large effects

there is a rainforest in BC that's survival relies on the nutrients that salmon bring when they spawn and die

It could also be scare mongering and have no negative effect, could be a net positive??
