Using unity 2017.4.35, expecting 10 clones but only 1 shows

I am trying to run a c# script onto a Person object and expected to show 10 clones at random locations, however only showed 1.

Here is Population Manager.cs:

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class PopulationManager : MonoBehaviour {

    public GameObject personPrefab;
    public int populationSize = 10;
    List<GameObject> population = new List<GameObject>();
    public static float elapsed = 0;


	// Use this for initialization
	void Start () {
        Vector3 pos = new Vector3(Random.Range(-9, 9), Random.Range(-4.5f, 4.5f), 0);
        GameObject go = Instantiate(personPrefab, pos, Quaternion.identity);
        go.GetComponent<DNA>().r = Random.Range(0.0f, 1.0f);
        go.GetComponent<DNA>().g = Random.Range(0.0f, 1.0f);
        go.GetComponent<DNA>().b = Random.Range(0.0f, 1.0f);
        population.Add(go);
	}
	
	// Update is called once per frame
	void Update () {
		
	}
}

How could I fix this issue?

The reason why it’s creating a single clone is because the code is creating only a single object. Put the code to create clones inside a loop like this.

void Start () {
	for(int i = 0; i < 10; i++){
  	Vector3 pos = new Vector3(Random.Range(-9, 9), Random.Range(-4.5f, 4.5f), 0);
        GameObject go = Instantiate(personPrefab, pos, Quaternion.identity);
        go.GetComponent<DNA>().r = Random.Range(0.0f, 1.0f);
        go.GetComponent<DNA>().g = Random.Range(0.0f, 1.0f);
        go.GetComponent<DNA>().b = Random.Range(0.0f, 1.0f);
        population.Add(go);
	}
}
