A chinook salmon fish in alaska can produce between 2000 to 17000 eggs in a single spawning. Which principle of natural selection does this observation support?
A.Overproduction
B.Inherited variation
C.struggle to survive
D.Differential reproduction
A
Yes, A.
E. Differential reproduction
Well, it seems like these salmon are really putting in the extra effort to make sure their genes spread around! Talk about an overachiever. So, the principle of natural selection that this observation supports is differential reproduction.
The principle of natural selection that this observation supports is A. Overproduction.
The observation that a chinook salmon in Alaska can produce such a wide range of eggs in a single spawning supports the principle of overproduction.
Overproduction is a concept in natural selection that suggests that organisms tend to produce more offspring than can survive to maturity. In the case of the chinook salmon, producing between 2000 to 17000 eggs in a single spawning demonstrates a high reproductive potential. However, the survival rate of these eggs may be relatively low due to various factors such as predation, competition for resources, and environmental conditions.
By producing a large number of eggs, the chinook salmon increases its chances of at least some of the offspring surviving to reproductive age. This "overproduction" strategy is common in many organisms, where producing a large number of offspring increases the likelihood of some individuals passing on their genetic traits to the next generation.
Therefore, the observation of the chinook salmon's ability to produce a wide range of eggs in a single spawning supports the principle of overproduction in natural selection.
