Background Info Rainbow trout go through a unique genetic reproductive process. Female eggs are diploid, while male sperm are haploid. In the wild, when the sperm fertilizes an egg, the extra set of chromosomes is kicked out, resulting in a diploid offspring. Triploid trout are produced in the lab to provide sterile fish stock for lakes. Shortly after the eggs are fertilized, scientists place them in a warm water bath to prevent the extra chromosomes from being removed. The result is a triploid fish that cannot reproduce. Rainbow Trout: n = 30 Global warming is an issue affecting many species around the world. Warming has caused the temperatures in lakes and rivers to increase and stay elevated for longer periods of time. Question Select the FOUR numbers that describe the possible effects of global warming on the reproduction of rainbow trout in the wild and on biodiversity. The extra set of chromosomes remains. The extra set of chromosomes is removed. The offspring are diploid (2n). The offspring are triploid (3n). The offspring cannot reproduce. The offspring can reproduce. Biodiversity decreases. Biodiversity increases.
