for a biologist studying a small fish population in the lab, which hardy-weinber condition is easiest to meet?
no selection
√ random mating
no genetic drift
no gene flow
no mutation
question 3

Explanation:

For Question 2 (large flatworm population, hardest Hardy - Weinberg condition):
Hardy - Weinberg equilibrium has conditions: no mutation, no gene flow, no selection, random mating, and no genetic drift (large population to avoid drift). In a large population, genetic drift is minimized, but random mating is hard to enforce as organisms may have mating preferences. For a large flatworm population, ensuring random mating (where individuals mate without preference) is difficult as flatworms might have behavioral or environmental factors influencing mating.

For Question 3 (small fish population in lab, easiest Hardy - Weinberg condition):
In a small lab - reared fish population, controlling mutation (no mutation) is hard as mutations are random. Controlling gene flow is easy (lab environment, no external genes). No selection: can be controlled by providing uniform environment. Random mating: can be managed in lab. No genetic drift: hard in small population. But "no gene flow" is easiest as the lab is a closed system, so external genes can't enter easily.

Answer:

Question 2: random mating
Question 3: no gene flow
