Answer: The population having one large claw will have more offspring as compared to the ones having smaller claw.
Explanation:
A population of crabs has two types of crabs in it, one with larger claw and other with smaller claw. They will try to attract the female crab in order to mate.
The males having larger claw are more attractive to the females. Females choose to prefer larger claw over smaller claw because they will have a big burrow which will help her incubate her eggs and they are older (survivor)because the crustaceans grow majority of their life.
So, the crab with large claw is likely to have more offspring than other one.
From the dichotomous key, the result would be STURGEON FISH.
